Solved

I am trying to run a function using the cognite API. My understanding is that in order to do that I must first create a session to get the nonce. I am running into an error when I try and post to that api:  HTTPError: 401 Client Error: Unauthorized for url: https://az-eastus-1.cognitedata.com/api/v1/projects/pinnacle-dev/sessions I have confirmed that my group has permission to create sessions, I have confirmed that I am able to do other things with the api such as list assets, and also I am able to create a session in the SDK using client.iam.sessions.create() using the same client_id and client_secret. Any ideas where the authentication error would be coming from? Here is what my code looks like url = f"{BASE_URL}/sessions"print(url)headers = {    'Autherization': f"Bearer {access_token}",} data = {    'items' : [        {            'clientId': CLIENT_ID,            'clientSecret': CLIENT_SECRET,        },    ]} response = requests.post(url, headers=headers, data=data)response.raise

Hi, I am on Data Scientist Learn training. I´m getting the 404 Not Found error whenever I try to make a GET request for publicdata project. That´s the URL I´m trying to use{{baseurl}}/api/v1/projects/{{project}}/assets I also replaced {{project}} with ‘publicdata’ with same result.

Hi,I have added new metadata fields under CDF events. However, the metadata values sourced from SAP contain line breaks between sentences, which are currently not being preserved in the CDF metadata section.Please review and advise on how to ensure the original formatting, including line breaks, is retained in CDF.ORIs it a CDF nature to remove those line breaks?

Hi!I´m getting the warning below after c.data_sets.list() when using the SDK. it is important to mentioned that I successfully logged in using device autthentication and confirmed connection with client, but it is not possible to retrieve data. Can anyone help?Here the warning message: WARNING:msal.oauth2cli.authcode:Found no browser in current environment. If this program is being run inside a container which either (1) has access to host network (i.e. started by `docker run --net=host -it ...`), or (2) published port 53000 to host network (i.e. started by `docker run -p 127.0.0.1:53000:53000 -it ...`), you can use browser on host to visit the following link.

Hi Cognite Team,I'm building a React dashboard using Cognite Data Fusion for my portfolio and would like to know if there are any demo projects available for working with CDF data.

Hi Cognite team,I understand that Atlas AI is not available in the PublicData project and is primarily for enterprise tenants.I’d like to explore whether there is any possibility of getting sandbox access, a developer trial, or demo environment where I can experiment with Atlas AI using example data.Could you please let me know if there are options for developers or small teams to try Atlas AI in a non-enterprise context?Thanks a lot!

Hi All… Curious if anyone has any experience creating a custom data model using NEAT and then loading that data model using the Cognite Toolkit?  What would the flow look like to make this happen? Thanks!Wayne

Hi,First of all, where can we get the OID Project public data API documentation, and what are the parameters we need to pass to fetch the data?My aim is to use OID public data to access any asset — for example, a pump set — and display its data and health status on a dashboard. The dashboard will be built using React, and for the backend we can use FastAPI with the Cognite SDK.

I am following the hands on training and it asks me to go to ‘Document Parsing New’ section but I get an access error. who should I contact to get me the appropriate access? 

Hi Team,Currently I am going through the  “Data Engineer Basics - Integrate- PostgreSQL Gateway” training. Before this starting there is prerequisites setup to be completed, for that the link is provided but the link is broken. Its not working.Find the ref below -   

Hi When testing some new functionality in a Cognite Function I got this error message: “The size of the data field is too large.”The data input was from the output of another function ran previously in a workflow.I am looking through the documentation to find what the limits are, but can not find anything.For my use case I can decrease the input size and run more batches, but it would be good to know what the size limits are for input data into Cognite Functions. Also, are there any other size limits I should be aware of?Thank you!Sebastian

hi guys,  can you please tell me the reason of the error below while API testing in Postman:any help is very much appreciated 

Hello I had one question not directly related to Neat. On Neat website we have mentioned the Data Modelling Principles. One of the principle says:“All data models are kept in its own SpaceThis follows from the principle of parsimonious model. By keeping each data model in its own Space, it is clear which concepts are part of the data model and which are not. It also makes it easier to manage access control, which should be with the team that owns the data model. In addition, this enables establishing a clear portfolio of data products an organization owns.”Now the question - We have spaces created per teams and we put all the models related to a team in that single space. So basically we are having more than one models in single space.Just wanted to confirm whether this follows the principle or its against principle ?The text above in principle is slightly ambiguous to us and hence this question.

Hello,I am testing streams and records in one of our projects, but I am getting “The user does not have any ILA streams capabilities.” error.I am also not able to add the capabilities for Streams and Records to my user group as I cannot see them in the capability type list 

If I want to establish a relationship between a specific data model (not the core or enterprise model) and assets like a "function location," Do I  necessarily need to bring all the views from the core or enterprise models into your domain data model?The goal is not to extend the core model but to create a reference from my domain data model to the asset, possibly using node_reference.For instance, if I have an inventory and want to relate materials to a local storage (which is represented as an asset in the enterprise data model), could I define a property in my domain model that references the enterprise asset.Example:graphqltype StorageLocation { location: String plant: CogniteAsset # Reference to the asset in the enterprise model } In this case, I am just creating a link between my domain model and the asset without needing to extend the enterprise model or bring its full view into my domain model , works? 

Hi all,I am building a solution model on top of  a domain model we already have in place for a project.The domain model contains all the instances we have in the project, but this consumer is only interested in a subset and would like some filters in place to ensure that they are only getting the subset of interest. One of the requirements is that a certain property is according to their project standards and has a minimum length for a property. I see that there is a Range filter to check if a numeric property’s value is within a specified range, but is there any way I can add functionality to get the values length for this property?

I have the following question regarding Containers,  Spaces and Instances. Let's say I have a Container named Well in the space A and all its instances are created in space B. When I delete container Well in space A and recreate it (because I want to change a column name for example): Does instance in space B are deleted as well? If they are not deleted, If I rerun the transformation to populate the new container again in space B with the new schema (same external_id) what state should I expect my instances to be in ? A merge of old and new schema? What is the best practice ? To delete container in its space and its instances in all spaces also? Thank you!  

This might be a basic question, but I often find myself uncertain about when to use CogniteDescribable in data modeling within Cognite Data Fusion.For example, let's say we have domain tables in our data model, such as MaterialType, which contains data from SAP and defines the types of materials we work with (e.g., code and description). In this case, would it be appropriate to implement CogniteDescribable to reuse common properties like name and description?What are the advantages of doing so? Does using CogniteDescribable provide any specific benefits—such as improved performance through indexing or partitioning—when used it containers?In summary, should I always use CogniteDescribable in these types of scenarios, or are there cases where it's better not to?

I’m using n8n AI agent builder to query CDF via an http request. The body of the request is:The request URL is https://westeurope-1.cognitedata.com/api/v1/projects/essc-sandbox-44/events{ "filter": { "startTime": { "min": 1751070336000, "max": 1751588736000 }, "dataSetIds": [7726848970162689] }, "limit": 1000}CDF seems to recognize the datasetid filter but not other filters like starttime as shown or others like Types. The result set returned is all events in that datasetid.I’ve also tried minstarttime and maxstarttime.ideas?  

Hi,Can someone please help to get access on Canvas.​​​​​​​Canvas Access Issue

Hello, We are considering storing a relational database table with more than 100 columns as Records.Since the maximum number of properties per container is 100, we need to define a single table across two or more containers.In this case, I would like to know how to write a query that allows us to freely filter records that have properties defined across multiple containers.Our goal is to query the Records data in a way similar to executing SQL on the original RDB table with over 100 columns.Based on my testing, the behavior was as follows, which is not what I intended:When using only properties from container A in the filter or sort: only records of properties from container A are retrieved. When using properties from both container A and container B in the filter or sort: an empty JSONL is returned.If this cannot be resolved with a single query, I would appreciate advice on what kind of post-processing could help achieve the desired result.

i want to take export of one table to another table but facing this datatype error .also tried with multiple datatype (like string , float and Bigint ) still same issue is coming.
