issue with printing output in terminal after adding functions to app.py, content_generator.py and generator_utils.py

I have added some new functions for adding tags, inserting photos, and adding new page sections in three different files: app/app.py, app/models/content_generator.py, and app/utils/generator_utils.py. However, when I run the program using flask run, there is no output printed in the terminal.

I would greatly appreciate it if someone, particularly Wesley, could take a look and help me troubleshoot the issue.

Here is the link to my branch: https://github.com/howard989/data-magic-h/tree/add-functions.

Thank you very much.
