Could not find data model

Hi,

I have a datamodel in CDF and I want to run a GraphQL query through the SDK to retrieve specific data from the model. When I try to run 

response = client.data_modeling.graphql.query(
    id = ('sp_watercourse_data_model', 'Watercourse', 'v1'),
    query = query
    )

I receive the following error message:

CogniteGraphQLError: [GraphQLErrorSpec(message=Could not find data model with space=sp_watercourse_data_model, externalId=Watercourse and version=v1, locations=[], extensions={'classification': 'DataFetchingException'})]

However, when I list my models using

models = client.data_modeling.data_models.list(limit=100).to_pandas()

the model is in the dataframe as expected.

 

What causes this problem and how can I fix it?

 

thanks

​@Jørgen Aarstad can you please check whether the version of the data model is v1 or 1?

Try again using the below code and let me know whether you are able to run it?

response = client.data_modeling.graphql.query(
    id = ('sp_watercourse_data_model', 'Watercourse', '1'),
    query = query
    )

​@Jørgen Aarstad can you please let me know the SDK version that you are currenly using? Have you checked whether data_modeling.graphql.query is working for other models?

I’m using v7.73.6. It doesn’t work for any other models, either

I tried from my end with the SDK version 7.73.6. It worked as expected. I was not able to reproduce the issue that you are observing. I’ll further investigate and get back to you with an update.

​@Jørgen Aarstad I also tested this function now and had no isuses.

When you define the data model to query against, the tuple is (space, external_id, version) of the model, can you please verify that the middle parameter is the external_id and not the name of the data model? This are often similar but still not equal.

If you still experience problems there is a debug flag in the SDK (doc) that will print the API request. From this you can obtain the path and compare against against what you see in the query explorer in the Fusion UI.

 

Let us know how things go.

 

Regards,

Arild Eide
