Solved the error above! Notice I am using https
instead of http
for the localhost url. And that server was treating this as a Bad Request. Removed the s
and everything worked as expected! :)
Hahahahaah this just happened to me, took me finding this message after 40 mins of research
Add _scheme='https'
in url_for(...)
. This will make a URL and redirect it.
A solution while getting Bad Request
when you use https
instead of http
.
Hope it does help you. 🙂
