"TypeError: object of type 'map' has no len()" error when adding django_social to INSTALLED_APPS - python-social-auth

Question

I am tryging to implement django social auth, and to do that I did pip install social-auth-app-django, then I went on to add social_django to my INSTALLED_APPS. After that when I am running the app, I am getting the following error (I am submitting the entire traceback):

If I comment out the 'social_django' from the INSTALLED_APPS, everything works fine again.
My python version is 3.5.2, and Django 2.2.12. Any ideas ? I am lost...

I faced this error , I fixed it by uninstalling both python-openid and python3-openid :
pip uninstall python-openid
pip uninstall python3-openid
then re-install python3-openid using:
pip install python3-openid
