404 when accessing resource Flask-Restful
Ok, the problem seems to be that the below ordering is wrong. I must add resources before I init the api.
api = Api()api.init_app(app)api.add_resource(HelloWorld, '/')
Fix:
api = Api()api.add_resource(HelloWorld, '/')api.init_app(app)
This is quite strange given that e.g. SQLAlchemy needs to call init_app before it is used...
