Refresh identity exception in sentry internal

I’m using sentry on-premise with Google Auth, I’ve configured Google auth and it works and i’m able to login with it.
I have on internal project over 500 errors with exception

AuthIdentity(id=4) returned an error during validation: HTTP 400 (invalid_request): Could not determine client ID from request.

referring to file
sentry/auth/providers/oauth2.py in refresh_identity at line 219

        # an invalid grant when a user is suspended
        if error == 'invalid_grant':
            raise IdentityNotValid(formatted_error)
    if req.status_code != 200:
        raise Exception(formatted_error)

I have the CLIENT ID and i’m sure that it’s working because i can login, but i can’t figure out what is wrong.

version used 9.1.2
