Body

Environment:

• Django Version: 4.2.11
• Python Version: 3.11.3
• django-gmailapi-backend Version: 0.3.2

Issue Description:
After setting up django-gmailapi-backend to send emails through my Django application using Gmail API, the first time it was working, now it's not working, I consistently encounter a RefreshError with an 'invalid_grant: Bad Request' message during the OAuth2 token refresh process. This occurs when attempting to log in via the django-allauth package, which triggers an email confirmation send action.

Despite redoing the refresh token procedure, ensuring the correct setup in the Google Cloud Console, and double-checking the client ID and secret, the issue persists.

Error Message:

google.auth.exceptions.RefreshError: ('invalid_grant: Bad Request', {'error': 'invalid_grant', 'error_description': 'Bad Request'})

Steps to Reproduce:

1. Set up django-gmailapi-backend with OAuth2 credentials according to the documentation.
2. Attempt to log in through django-allauth, triggering an email action.
3. The error occurs during the OAuth2 token refresh attempt by django-gmailapi-backend.

I also use the official script of google, because the link output generated through gmail_oauth2 saying that I cant get or connect when using gmail_auth command line

https://raw.githubusercontent.com/google/gmail-oauth2-tools/master/python/oauth2.py

I have made all the combination of https/http - localhost/127.0.0.1 - with port 8000 or without it

Expected Behavior:
The refresh token should be successfully used to obtain a new access token, allowing the Gmail API to send emails without encountering a RefreshError.

Actual Behavior:
The refresh token process fails, resulting in an invalid_grant: Bad Request error, preventing email sending through the Gmail API.

Additional Context:

• OAuth consent screen configuration, project API access, and library versions have been verified.
• The issue persists even after generating a new refresh token.

I have a secret file where i store the JSON
all the necessary settings have been filled :

EMAIL_BACKEND = "gmailapi_backend.mail.GmailBackend"
GMAIL_API_CLIENT_ID = Secrets.GOOGLE["web"]["client_id"]
GMAIL_API_CLIENT_SECRET = Secrets.GOOGLE["web"]["client_secret"]
GMAIL_API_REFRESH_TOKEN = Secrets.GMAIL_API_REFRESH_TOKEN
DEFAULT_FROM_EMAIL = Secrets.EMAIL_HOST_USER

Questions:
Has there been a recent change in the Gmail API or Google's OAuth2 implementation that could affect token refresh behavior?

I appreciate any guidance or updates that can help resolve this issue.
I'm realy lost - I'm don't know if the wrong is at google or my code or my secrets, credentials...
Thank you very much in advance - as now I can't access to my app since it try to send the confirmation email through allauth as my database was cleaned - up so it's like the first access to the app

For debugging purposes, is the email you're using for the backend the same one you are logging in with in allauth?
