I have a helper function that returns a CogniteClient via interactive OAuth authentication. This worked literally yesterday, but gives me an error today.
This is my function definition
import os
from cognite.client import CogniteClient, ClientConfig
from cognite.client.credentials import OAuthInteractive
from typing import Union
def authenticate_to_cognite_oauth(
project: str="akerbp",
client_name: str="Employee",
client_id: Union[str, type(None)]=None,
tenant_id: Union[str, type(None)]=None,
base_url: str="https://api.cognitedata.com"
) -> CogniteClient:
"""Authenticate to Cognite via OAuth interactive login.
Return cognite.client.CogniteClient."""
if client_id is None: client_id = os.getenv("CDF_CLIENT_ID")
if tenant_id is None: tenant_id = os.getenv("CDF_TENANT_ID")
authority_url = f"https://login.microsoftonline.com/{tenant_id}"
scopes = [f"{base_url}/.default"]
creds = OAuthInteractive(
authority_url=authority_url,
client_id=client_id,
scopes=scopes
)
config = ClientConfig(
client_name=client_name,
project=project,
credentials=creds,
base_url=base_url
)
return CogniteClient(config)
I use this function in the following way (auth function stored in auth.py)
from auth import authenticate_to_cognite_oauth
from deploy import external_id
client = authenticate_to_cognite_oauth(
project="akerbp-sandbox"
)
call = client.functions.call(external_id=external_id)
print(call.get_response())
The error traceback is given below. It is not able to verify the credentials, as it is NoneType instread of type Dict[str, Any]. What might cause this all of a sudden?
