"detail": "Method \"GET\" not allowed."

[FG-Samuli]

Hi.
I'm newbie to auth.
dj-rest-auth seemed easy enough to implement my existing project.

I followed this guide (Django REST APIs with JWT Authentication using dj-rest-auth, Michal Dróżdż)
/api/v1/auth/user/ returns 401 unauthorized.
That's ok

/api/v1/auth/login/ returns 405 "detail": "Method "GET" not allowed."
This is not.

I'm using Postman. If I try to POST on Swagger it works and returns access token.

Where should I start looking for the problem?
