Facebook Login Bug

Hi, I’m trying to have facebook login on my instance. For that I’ve set up a Facebook developer app and followed the tutorial however, I get following error when trying to log in via Facebook. Please help someone as I’ve been bugging my head over this for quite a well now.

Hi to copy and paste your traceback code here means easier code browsing, and forum searches for code text then work too thanks!

edit: But be sure to remove sensitive identifiable stuff like email addresses, and staff names and so on…

facing same issue. did you find solution?
