Google Login view returns 500 on invalid or multiple inputs

[hsalimi79]

Hey there 👋

I noticed that the GoogleLogin view throws a 500 error under certain input conditions. Specifically:
If both access_token and code are sent together in the request, the server crashes with a 500 error.
If an invalid access_token is sent on its own, it also results in a 500.

This happens consistently and seems like the view isn’t handling these edge cases gracefully. Here’s what my view looks like:

class GoogleLogin(SocialLoginView):
    adapter_class = GoogleOAuth2Adapter
    callback_url = settings.GOOGLE_AUTH_CALLBACK_URL
    client_class = OAuth2Client

Ideally, these should return a 400 Bad Request or a meaningful validation error instead of a server error.
🔍 Example Inputs That Trigger 500

Case 1: Sending both access_token and code

{
  "access_token": "fake_token",
  "code": "fake_code"
}

Case 2: Sending only an invalid access_token

{
  "access_token": "invalid_token"
}

Both of these cases consistently return a 500 response.

If you're open to it, I’d be happy to try fixing it and submit a PR 😊 Let me know!
