I'm trying to use a graphql query in my python notebook. And I'm using this code snippet given in the sdk docs.

 

from cognite.client import CogniteClient
>>> c = CogniteClient()
>>> res = c.data_modeling.graphql.query(
...     id=("mySpace", "myDataModel", "v1"),
...     query="listThings { items { thingProperty } }",
... )

 

I dont see data_modeling.graphql.query() method available. I see the below error message.

 

AttributeError: 'DataModelingGraphQLAPI' object has no attribute 'query'

 

I'm using sdk version 7.5.1. How do I run my grapghql query?

Looks like recently this got fixed, from this PR- https://github.com/cognitedata/cognite-sdk-python/pull/1548. I have updated my SDK to the latest but still no go with fetching the data from the data model. my query looks like this
 

query MyQuery {
  listCapacity {
    items {
      plant {
        latitude
        longitude
        name
        plantLocation {
          name
        }
      }
      timeSeries {
        dataPoints(start: 1698793200000) {
          value
          timestamp
        }
        unit
        metadata
      }
    }
  }
}

Using the query as such returns the below result.

{'listCapacity': {'items': []}}

If i use the query like how it is mentioned in the sdk docs by trimming the initial part of the query `query MyQuery {`

I get the below error
 

cognite.client.exceptions.CogniteGraphQLError: [GraphQLErrorSpec(message=Invalid syntax with offending token 'listCapacity' at line 1 column 1, locations=[{'line': 1, 'column': 1}], extensions={'classification': 'InvalidSyntax'})]

@Dilini Fernando  The primary issue was the sdk version. The version 7.5.1 didn’t have the method query() implemented. I guess it was included in the recent release (7.6) which i learnt from that pull request mentioned. Why I mentioned it didn’t work even after updating the sdk is kind of mystery, I suspect it could be a query formatting issue.
