In number of methods in the code current_user is fetched like this: `user_id = current_user["sub"] if current_user != None else None ` If a user is logged this fails with error: ` line 96, in get_current_user raise RuntimeError( RuntimeError: You must provide a `@jwt.user_lookup_loader` callback to use this method ` My solution is to add the callback method in `api/__init__.py` right after JWTManager is initialized like this: ``` jwt = JWTManager(app) @jwt.user_lookup_loader def user_lookup_callback(_jwt_header, jwt_data): return jwt_data ``` I am using python==3.11, Flask==2.2.2, Flask-JWT-Extended==4.4.4 as per requirements.txt.
