Error on docker ValueError: The name 'Items' is already registered for this blueprint. Use 'name=' to provide a unique name

I am currently building an API on VS Code using Python 3.11, Flask, Insomnia, and Docker.

when I tried to create my resources file to use flask_smorest I am getting this error on Docker

ValueError: The name 'Items' is already registered for this blueprint. Use 'name=' to provide a unique name.

Insomnia is also giving me a value error indicating "Items" is already registered for this blueprint.

I am learning right now and am not sure how to find out where the blueprint is being used twice so that I can change it and move forward with my course.

Thanks!

I am not sure how to find out where the first blueprint was created or how I duplicated the blueprint anywhere in the above code. I am hoping someone can offer assistance.

I have restarted this part so many times already!
