TemplateDoesNotExist graphene/graphiql.html

Question

I'm trying to setup Graphene, but have a following exception raised when open http://localhost:8000/graphql/ in browser:

TemplateDoesNotExist at /graphql/
graphene/graphiql.html
Request Method: GET
Request URL:    http://localhost:8000/graphql/
Django Version: 3.2.10

Added did whole setup, added to urls, configured schema, queries and mutations. But still not work. And even don't remember that ever needed to configure templates for Graphene.

Answer 1

Looks like forgot to add following in settings.py, so it wasn't fully configured, at least for DEBUG mode:

INSTALLED_APPS = [
    # ...
    "graphene_django",
    # ...
]
