I am also getting this exact error. My credential file works as expected with gcloud and the google genai python api. ``` litellm.APIConnectionError: Invalid Identity Pool credential_source field 'environment_id' ```

I was able to fix the issue by not passing credentials to the `litellm.completion` as shown in the docs and setting the following two environment variables * `GOOGLE_CLOUD_PROJECT=your-project` * `GOOGLE_APPLICATION_CREDENTIALS=path/to/credentials.json`
