The scenario is,
I cloned the Django code for OpenShift-V3 from here . When I run the code using python manage.py runserver
getting an error as,
I was using django-cors-headers, then I thought I haven't implemented cors in my project, so went ahead to install django-cors-middleware, then it's started giving the wsgi exception, so i checked the stack trace and I found out that it's django-cors-headers and django-cors-middleware conflicting each other. I had to uninstall django-cors-middleware but it's still gives the same exception, so uninstall django-cors-headers too then reinstall and everything works fine....
I used a middleware CorsMiddleware but forget to install it so after install, it works perfectly.
pip install django-cors-headers.
So check something like it you may miss something like it.
