[yangjinghit]

i got the same issue, have you solved it ? @janaka1984

[yangjinghit]

Flask==1.1.2
Flask-SQLAlchemy==2.5.1
Authlib==0.14.3
this version is ok

[TechStudent10]

I think the issue is in websites/routes.py. Change this line:

bp = Blueprint(__name__, 'home')

to this line:

bp = Blueprint('home', __name__)

and it should work.

[lepture]

updated the demo. Thanks @TechStudent11

[TechStudent10]

@lepture no prob :)

[bera-bin-le]

@lepture the main branch README still has the wrong example code (the Hello World section).
