I’m unable to use the Microsoft Authenticator app on my new phone, as my previous phone has been sold.I need to access the public data instance for the Cognite Flows workshop, but authentication is required to log in. Since I’m unable to receive or approve the authentication request on my phone, I’m currently blocked from accessing the instance.Could you please help me resolve this authentication issue so I can access the public data instance and proceed with the workshop?

Hello! I have got a new phone and am not able set up the authenticator app again.Could you please help with the set up.Thanks,Rahul

Hello everyone,  I am in the transformation part in the Cognite Fusion Data Fundamentals Part 2 - Hands-on. I ran a transmation as asked but it doesn´´t appear in the filter

How can we get access to work hands-on with the learning path athttps://cognite-learn.fusion.cognite.com/cdf-fundamentals/data-models?cluster=api.cognitedata.com&workspace=data-management?If not, how can we practice hands-on with Cognite Learn?

Hi Community,Has anyone successfully configured the Cognite DB Extractor to connect to Databricks via ODBC using a service principal?I was able to connect to Databricks using a Personal Access Token (PAT), but I am experiencing issues when trying to authenticate with a service principal.Any guidance or examples would be greatly appreciated.Thanks in advance,Andre

Hi, I am trying to set up a routine in GAP, but the run fails due to missing variable in the command, and I cannot set the value specifying which calculation to run. Can anyone explain how to fix this?This is a screenshot from GAP, and I want to select one of the Allowed Values:This is a screenshot in CDF showing that there is no field to enter that:The error message:  

Hi, could you please help me to register MFA using Cognite to do bootcamp prep hands on session?

Hello!We have encountered some issues with backfilling on the PI Extractor. This usually goes automatically, and works fine. However, we do now have a 2 day gap in data on Cognite, however all that data is present in PI.Are there any way to “force” a backfill, or fix this issue somehow?Thanks! 

Is it possible to remove a Flow App from a Cognite cluster after it has already been deployed?

I am not able to find any documentation for deactivating and/or deleting Flows custom apps on docs.cognite.com, I’d say that this is a very important part of the life cycle and should be included in that section.I do see that the feature exists in the CLI, which is good, otherwise this would be a different request: 

HiWe've hit a bug in cdf-tk (reproduced on 0.8.147 and 0.8.155) when deploying containers to a brand new space.We have 98 containers in a new space. One container has no constraints, but others reference it via a requires constraint pointing to the same space. cdf-tk sends all containers in a single batch. The CDF API seems to validates requires constraints against what already exists in CDF not against other items in the same batch so it rejects the entire batch with this error:Cannot create requires constraint 'requireMetadata' in container'sp_xxx:ContainerB'.Target container 'sp_xxx:ContainerA' does not exist.cdf-tk should sort containers by their requires dependencies before batching, so dependency free containers like containerA are sent before the containers that depend on them.We'd appreciate a fix in an upcoming release, or any insights regarding this issue.Thanks

Hello,  the default value for autoCreateDirectRelations for node creation is True. Cdf toolkit do not expose this config at transformation level today. This results into uncontrolled ‘empty’ instance creation when direct relationship nodes does not exist.Do you plan to expose this config to cdf toolkit so we can change the default behaviour?ref: https://docs.cognite.com/20230101/instances/create-or-update-nodesedges#body-auto-create-direct-relations Thanks Best,

We are migrating to the core data model. Time series we tested. We can ingest CogniteTimeSeries directly from the OPC-UA extractor. Assets are in progress.Sequences are our open question. We use them heavily for three things:Multi-dimensional rows tied to a timestamp or time range, where one time series per dimension is the wrong shape. Static reference data that many Functions read. Schemas where one data modelling instance per row would explode our instance count — short heating episodes, small production batches, and similar.What makes them attractive is the combination: readable in the UI, integer indexing, cheap, fast, and metadata slots both per column and per sequence.Looking at the core data model reference, I see no sequence concept — CogniteTimeSeries, CogniteActivity, CogniteFile and so on are all there, but nothing for tabular data. We have noted CogniteTimeSeries with type: state and CogniteStateSet, which covers state classification, but not the multi-column case.So:Is a

Hi Team,We are currently exploring migration of our existing content to use Flexible Data Modeling in CDF, and we are facing some challenges while configuring the OPC UA Extractor.At the moment, we are still pointing the extractor to the traditional Asset-Centric Time Series (dataset-based approach) and then transforming the data into our Data Model types afterward. However, we would like to ingest data directly into a view that implements the CogniteTimeSeries type.We would appreciate your guidance on the following: Do you have any example .yml configuration for the OPC UA Extractor that ingests data directly into a view implementing CogniteTimeSeries? Are there any best practices or recommended approaches for this setup? Is the following documentation the correct reference for this use case?https://docs.cognite.com/cdf/integration/guides/extraction/configuration/opcua#data-models Additionally, we are also evaluating OPC Events ingestion: Should OPC Events be modeled using Cognite

I have exactly the same issue that in Cognite Hub, somebody solved it and said: “I’ve revoked your MFA so you will have to re-register it for our Hub tenant” could you please helping me revoking the MFA and please explaining me how to re-register? thanks.

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 everyone,I'm currently taking the "Introduction to CDF & Grafana" course on the Academy, but I've hit a roadblock due to a mismatch between the tutorial videos and the current UI. It looks like the Grafana UI and the underlying Cognite plugin have changed significantly since the course videos were recorded, and I'm stuck trying to plot my data.Here is a breakdown of my current setup and where I am getting blocked:Current Setup & Connection Course Reference: Introduction to CDF & Grafana (specifically the hands-on video tutorials for dashboard creation). Connection Status: The connection to the CDF database (cognitedata-datasource) is active and successfully authenticated. The IssueThe updated UI dropdowns now primarily expose modern Data Modeling spaces (such as CogniteTimeSeries (cdf_cdm) v1, CogniteExtractorTimeSeries, etc.).Because the UI seems locked into searching within these specific, unmapped modeling spaces, I cannot retrieve my classic data: I've tried search

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

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 

On a user.Group.yaml file we are able to set specific ids to certain capabilities, such as datasets:  - datasetsAcl: actions: - READ scope: idScope: ids: - datasetId1 - datasetId2 Are we able to also do this for agents via agentsAcl run? I couldn’t find anything specifying it in the documentation and the assistant claimed it was not possible. I wanted to double check here if someone knew more about this.

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?
