Please help with Awesome Django Comprehensive Comparison of Python Web Frameworks

I went to the Educational Section of Awsome Django and selected to work on the second link- LearnDjango - Tutorials and premium courses on Django and Django REST Framework. I decided to start learning from the very beginning, the first tutorial- Flask vs Django in 2024: A Comprehensive Comparison of Python Web Frameworks. To follow along I created a directory “learndjango1” to hold all my work from the LearnDjango tutorials. I then created another directory “Flask” inside the learndjango1 folder
I think I followed the tutorial instructions up to where I am to run the ‘flask run’ command. When I run the ''flask run
command I get the following error

Try 'flask run --help' for help.

Error: Could not locate a Flask application. Use the 'flask --app' option, 'FLASK_APP' environment variable, or a 'wsgi.py' or 'app.py' 
file in the current directory.

What is the contents of your app.py file? (Or, if you named it hello.py as it appears to say, I believe the command you need to use would be flask run --app hello.)

Edit: The command would be flask --app hello run

@KenWhitesell . Thanks for your suggestion. I was able to get the development server up and running. However when I control clicked the 127.0.0.1:5000 I got this error- Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

What do you think a cause of this might be?

What do you think are two things we might need to see to try and hep you with this?
