KeyError: 'grant_types_supported' with weaviate.AuthClientCredentials

[kendistiller]

It seems that the Python client is checking for client_credentials in the optional grant_types_supported field for the discovery response.

/weaviate/venv/lib/python3.7/site-packages/weaviate/connect/connection.py", line 201, in _set_bearer
    if 'client_credentials' not in request_third_part.json()['grant_types_supported']:
KeyError: 'grant_types_supported'

However, our OpenID Connect provider Azure AD does not provide this optional field in its discovery response (apparently).

Yet we are able to authenticate to Weaviate with OIDC via the REST API just fine (and perform read/write), so we would expect the Python client to (hopefully) behave the same.

Here is connection excerpt from the Python client:

client  = weaviate.Client(
    url='http://localhost:8080',
    auth_client_secret=weaviate.AuthClientCredentials(access_token)
)

Hi @kendistiller, as the issue is with the python client we will transfer this issue over. We are working to provide documentation for using Weaviate with Azure AD.

Hi @kendistiller ,

I think this (PR and build) will fix your issue. You have two possibilities:

• Add the access token you got yourself

client = weaviate.Client(
        url=URL, auth_client_secret=weaviate.AuthBearerConfig(ACCESS_TOKEN)
    )

• Let the python client get the access token

client = weaviate.Client(
        url=URL, auth_client_secret=weaviate.AuthClientCredentials(client_secret=CLIENT_SECRET, scope=SCOPE),
    )

(We have a hardcoded scope for azure. But if you supply one, yours has precedent.)

merged, please let us know if this doesn't fix your error
