hi, I am taking up the course for data modelling and facing some issues for transformation.Have created an asset named Dutta2026 and while running transformation I receive the error below. Can somebody help me troubleshoot it please? I think it is some kind of access block. [ASSETS] Request with id a8ff7523-7c66-9300-82e5-37961456d56d to https://api.cognitedata.com/api/v1/projects/cdf-fundamentals/assets failed with status 403: Resource not found. This may also be due to insufficient access rights.
I used the Atlas AI agent (default) to locate two timeseries, and then clicked on the “add to dashboard” button. The chart got added, and the title indicates both are added, but the chart only has a single visible line. If I move the mouse pointer down, it snaps to another value (notice the location of the blue point), but not sure if this is the other timeseries or if it is a spike from the raw data that is not shown due to downsampling on the chart. Also, the time range selection do not change the timerange for the chart
We are getting data from PLCs onto Kepware, then using the OPC UA Extractor to send that data to FTDM. Once the data is in FTDM, I have another application that consumes data from it. The issue is that we are getting an array of boolean values in Kepware. If we extract the array values, the number of tags becomes too high. Therefore, we are looking for ways to transform or encode the array into a singular timeseries. Our initial idea was to convert the array into a string, then converting it back to an array in our application. Another idea is to encode the array into a single large integer. But I can’t see any avenue of doing either of these in the extractor. Any ideas on how to do so?
When dropping a file from your desktop/drives into Canvas, the file size increases. As one example, it went up 30 times; from 84kb --> 2520kb (without the canvas coverpage). The file size change makes it difficult to download the canvas, as it gets stuck. The end users cannot download the canvas they create and therefore are prone to stop using the platform.
Hi Team,It was observed that List and Search queries have some functional limitations which are handled explicitly by teams. Below are the expectations: Search queries must support pagination, enabling users to retrieve results beyond the current 1000-record limit. Pagination should include a cursor or offset mechanism, allowing seamless navigation through large datasets without data loss or duplication. List queries must support case-insensitive filtering Users need substring search over large datasets, which is not fully supported. Can we provide feature like "Contains" which will allow substring search.Thanks,Rahul

Cognite Data Fusion (CDF) appears to enforce a limit of approximately 200 Azure AD group memberships when resolving permissions for Service Principals. This limitation does not exist in Microsoft Graph, which supports retrieval of all group memberships associated with a user or Service Principal.As organizations scale their authorization models using Azure AD groups, this restriction can prevent access inheritance from functioning as expected and requires manual workarounds that increase operational overhead and governance complexity.Business ContextMany enterprise deployments use Azure AD groups to manage access to assets, plants, data products, and other resources within CDF.A common architecture relies on: Azure AD groups representing access domains. Group Object IDs mapped to corresponding Source IDs in CDF. Service Principals inheriting permissions through group membership. However, when the number of group memberships exceeds the current supported threshold, some memberships
SummaryWhen building workflows in Cognite Data Fusion to populate views in Data Models, there is often a need for intermediate, curated datasets between raw source data and the final target data model.Today, this intermediate data can be stored in RAW tables, but that requires customers to manage temporary tables, cleanup logic, naming conventions, and lifecycle handling manually. A native, workflow-managed temporary storage layer would make workflow development cleaner, reduce repetitive transformation logic, and simplify the overall implementation. Business ContextWe are using CDF workflows to populate an Asset Hierarchy data model.The source data comes from multiple systems:SAP Functional locations Equipment AVEVA PI Tag metadata The target asset hierarchy data model contains the following views:Site Area Line Equipment System Subsystem TagThe source metadata arrives without the required treatment, standardization, or contextualization. Before writing to the final data model, the
If you have tests that assume the a specific result ordering in instance list or query results without specifying a sort order when querying for recently upserted nodes, you may in the future see that APIs can return results in a different order than they were upserted, and possibly see your tests fail.The change in ordering happens when we insert data in the DM graph, and is required to make sure we correctly serialise operations and avoid deadlocks when processing upsert operations. The previous implementation is prone to rare race conditions that, while not having been a frequent problem before, may become a problem now as we work to optimize DM API performance and add support for more sophisticated access control in instance upsert operations.While this change is observable if your test hard codes an assumption that items are returned in the same order that they were inserted, this behavior was never specified, let alone guaranteed. The API behavior remains in line with previously
Hi Team,We are working as a data platform team and there are multiple data product teams using our application. Each data product team has a different space to isolate their data. Is there a possibility to see the storage statistics restricted to space level? Clients also want to see “max number of concurrent requests”.
Hi all,The point is to get the possibility to enlarge the All Categories column in the Search. This should be useful if views names are too long to facilitate the navigation.
Atlas AI – agent building and chatbot notesThe GoodAble to switch between list and tile view as well as Search. Having a Description is helpful. Nice that there are sample questions. Loading feedback. Ability to stop generation. Legal disclaimer near prompt area. Nice that it shows reasoning steps. Like the suggestions with Show More Bot background color is fine. Reasonable area to write a prompt. Great to be able to view the details using the info icon of what each agent is good at before switching to it.Could be improvedPriority 1Starting a new chat is “risky” because there is no history, copy or chat download/export functionality. Part of the point is to aggregate information for analysis later, sharing or collaboration Chat history/multiple threads Need a way to set expectations up front so that when a new chat is started, we can orient users as to what can and cannot be done. Description helps but gets cut off. Sample questions as defaults are not injected but auto triggered. This
When opening the “Ask Assistant” the navigation bar disappears, this seems like a bug. I for one would like to have both at the same time.

Hi Team,I would like to request for a new feature from Cognite to provide the hard delete options of instances in FDM.Currently, the instances are by default soft deleted and if the soft delete instances limit is reached, no further ingestion is allowed in the Project.Issues faced in the past - We have a shared Cognite Project, which is being used by multiple teams, and one team was in process of migrating their data from SQL to Cognite FDM. In the process, transformations run successfully but few data were corrupted. So, they deleted the entire FDM dataset and performed the transformation again. Meanwhile the soft delete instances limit was reached, making the ingestion failure for all the teams using that project.Here, the first team wants to hard delete the instances however, with no option currently available left them with no choices. And the similar incident has occurred again.Hence, we are requesting to provide a feature to perform hard delete of instances, considering the perfo
When adding time series data to industrial canvas, providing the name of the tag and the description field in the time series tile window would clarify what tag is being shown. Submitted at the request of the Cognite project team.
Hi experts, In order to decide whether to use an aggregation strategy (or no aggregation at all), I need to know the number of data points between two timestamps without aggregation (server-side calculation). I’m looking for this code of call :client.time_series.data.count(external_id=<str>, start=<int | datetime>, end=<int | datetime>) -> intI'm trying to avoid having to perform a granularity calculation Thanks !Regards,Pierre
I would like to submit a product idea regarding Charts calculations.Currently, calculations in Charts are performed only within the time range that is visible on the screen. We would like to request an enhancement that allows users to define a specific calculation period (i.e., start and end points) directly within the calculation formula.For example, when using the “sample average” operator, the result is calculated only based on the data currently displayed. As a result, the calculated value changes when the user scrolls or shifts the visible time range.We would like to be able to calculate metrics such as average values over a fixed, explicitly defined time range, including data outside of the current view. This would ensure that the result remains consistent and is not affected by scrolling or changes in the displayed window.We believe this functionality would significantly improve usability and enable more stable and meaningful analysis.Thank you for your consideration.
Hi everyone,While querying the CogniteAsset view, I encountered an error when including the activities field in the selection. The API returns the following message: "Cannot traverse lists of direct relations inwards." Upon investigating, I noticed that the activities field in the CogniteAsset view is defined as a @reverseDirectRelation: activities: [CogniteActivity] @reverseDirectRelation(throughProperty: "assets") In turn, the assets field in the CogniteActivity view is defined as a list of direct relations:assets: [CogniteAsset] @directRelationThis makes sense as the root cause, since reverse traversal over a list of direct relations is not allowed, which explains the error.Given that this field leads to an invalid query pattern and always results in an error, should the activities field be removed from the CogniteAsset view to avoid confusion and runtime errors? Here’s a minimal query that reproduces the issue:query MyQuery { listCogniteAsset { items { aliases activit
While working with a selection of time seies in canvas, I would like the ability to select a number of these to send to canvas in one action for further analysis. The way it works now I can send one time series to canvas and then have to search for the other time series i want to add to charts manually.
Currently, the search function starts only after entering a keyword and pressing Enter.Would it be possible to support incremental search, where results are updated dynamically as the user types?I believe that the “Data explorer” in Data Fusion (prior to the current Search feature) used incremental search.With incremental search, users can see results immediately, which makes it easier to try different keywords—especially for users who do not remember exact equipment names or file names. It also reduces the need to retype words.In addition, with the current behavior, there are cases where pressing Enter does not seamlessly trigger the search. In such situations, users need to click the search box again before pressing Enter, which can be slightly frustrating.On the other hand, I understand that incremental search may increase system load and could have performance implications. If introducing incremental search negatively impacts overall search performance, then the current implementat
When searching for assets or timeseries, there’s a feature in the detail tab that shows a list of Canvases where they’re used.↓Would it be possible to extend this to also show a list of Charts that use a given timeseries?Some example use cases:・Charts tend to be created in large numbers, so it’s sometimes hard to remember which Chart was used to create which visualization. Being able to trace Charts from a timeseries would make it much easier to reuse existing work.・Especially for scheduled calculation tags, it can be difficult to find the Chart where the original calculation logic is defined. It would be really helpful if we could trace back from the timeseries to the corresponding Chart to review the calculation.
We have an issue in our production system that influence many users. We have a app using JavaScript SDK where requests to the Group API times out. Can you please trace one of the request timing out: 492e1fee-234e-95eb-b371-8a11870708e8
I have 4 views that implement CogniteAsset. When clicking on an instance and heading over to the properties tab, there are four properties there:Asset class Name Asset class Description Asset class External Id Asset class SpaceThese are visible for 3 of the 4 views. Looking at the propertyLayout, I did not see any reference to an asset class in a view where they are visible, and neither in a view where they are hidden. I’ve tried adding the following to the PropertyLayout section of views where they are visible in the UI:- property: assetClass hidden: true But it did not help. What is the factor that determine whether these are visible or not?
