@crakernano @MajorTomaso Seems that the version of Flask-User expects a method 'get_user_by_token' with the same algorithm as load_user in the User model:

Hope this help!

Just got this error. Fixed with:

from flask_user import UserMixin

Then:

lingthio / Flask-User

type object 'User' has no attribute 'get_user_by_token' #301
