I am trying to implement a OAuth2 Workflow using google as identity provider. I have the following workflow.

My UI initiates the login flow by hitting the /auth/google/authorize endpoint and receiving the authorization url in the response.
UI Redirects to the auth URL and the OAuth login happens.
I have set my redirect URI to the one generated using fastapi_users i.e. /auth/google/callback. This API call gives me a 500 error with the following trace-back
The issue remains the same if I use a separate Redirect URI at my front-end which then calls my /auth/google/callback endpoint with the code and state.

FYI I have an empty DB and want to upsert the user after the OAuth workflow is successful.

Traceback (most recent call last):
  File "/home/onlinejudge95/.cache/pypoetry/virtualenvs/dicehub-backend-XcfLAgEF-py3.12/lib/python3.12/site-packages/httpx_oauth/clients/google.py", line 83, in get_id_email

    raise GetProfileError(response=response)

The above exception was the direct cause of the following exception:

If I drop the support for fastapi-users and do the login by hitting the API for authorize and user-info endpoint manually, then I am able to successfully perform the OAuth2 workflow.

I didn't encounter your issue when using it myself, so I really don't know what went wrong on your end.

I ended up removing it all together, directly integrating with the google API's work

I recently encountered the same "GetIdEmailError" issue after switching to the new GCP. I found that the response message indicated a lack of API permissions.

After enabling https://console.cloud.google.com/apis/library/people.googleapis.com, the issue was resolved.

This is likely because the integration using the Google SDK is not applying the same scope as in this file.

If anyone runs into the same issue, I recommend printing out response.json() to inspect the error message.
