Google Oauth2 refresh token error using python-social-auth

Question

I'm using python-social-auth and when I try to refresh my Google Oauth2 access token I get the following error:

[2017-02-15 14:41:00,089: ERROR/MainProcess] Task tasks.tasks.test_login[169e5810-489d-4134-af8f-db3b80629fd2] raised unexpected: HTTPError(u'400 Client Error: Bad Request for url: https://accounts.google.com/o/oauth2/token',)

    raise HTTPError(http_error_msg, response=self)
HTTPError: 400 Client Error: Bad Request for url: https://accounts.google.com/o/oauth2/token

I use the following code to refresh the access token:

from social.apps.django_app.utils import load_strategy

w_user = WUser.objects.get(auth_user=A('username','xxxx'))
social = UserSocialAuth.objects.get(user_id=w_user.auth_user.id)
strategy = load_strategy()
social.refresh_token(strategy)

Am I doing something wrong?

I had the same problem when calling social.get_access_token(load_strategy()). If you don't want to implement Google sign-in manually, I used this workaround which forces the user to re-authenticate to refresh their tokens.

try:
    strategy = load_strategy()
    access_token = social.get_access_token(ls)
except HTTPError as e:
    return HttpResponseRedirect(reverse('social:begin', kwargs={'backend': "google-oauth2"}))
