django social auth get wrong access_token from google oauth2

[petitchamp]

version 0.7.24
I am integrating google oauth2 to my website using django social auth. The problem is that with django social auth , I get an access_token like:

ya29.2QCqpS-uKGXMNOP8yZnN6Z-F5LfVnyd7jwa8TaLP43nTEp2NUPB_p7Hi

While with the code sample from google code the access token is like :

ya29.2QCVXKc7XSNR3QxqRVAi0Z8Uz6mvolDGpezbZ9_r_oq7CXt01WvE9oUb90HXaynOLE4J8PjA5pzYDB

The first one does not work while the second one works fine

does anyone have any idea on this ?

I even tried to compare the https request send to google , the parameters are identical same for url

I have completely no idea of this problem

This is python-social-auth, django-social-auth was deprecated and I'm not dedicating time to support it anymore.
