TypeError: argument of type 'function' is not iterable when starting django runserver

Question

When I try to run server, I get this following error:

Exception in thread django-main-thread:

EDIT: I've now uploaded the urls in my project. Thanks again. Im writing this text as my post is mostly code. Ive tried editing urls but that doesn't work so just looking for the solution.

I never had any problems before, I'm wondering if I accidentally changed something. Thanks.

Answer 1

I guess I found the error

re_path(r'^connect/(?P<operation>.+)/(?P<pk>\d+)/$', views.change_friends, name=change_friends)

The name must be a string so it shoud be like this

re_path(r'^connect/(?P<operation>.+)/(?P<pk>\d+)/$', views.change_friends, name='change_friends')
