Hello! I finished a python course and I'm working on a project but I have some problems.
The most urgent would be: after filling in all the fields in the register form and submitting I receive an error “NameError: name‘ app_ctrl ’is not defined”. How can I define this app_ctrl to recognize it?
The problem appeared after I created a main.py and _init.py file, when this main.py did not exist, my function worked, I could register accounts using postman.
I also attached 2 pictures with the structure of the application, templates.py, forms.py and routes.py I left them out I didn't put them in a View folder.
Please help me I'm stuck here for better it's been a week, I don't know how to change it to work.

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the “Traceback” headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.
You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:
