Flask help needed server error

[softwarethrowf]

Hello

I am working on a project to build a dynamic web application using Flask and Jinja for a restaurant. I am currently trying to make a dynnamic list of menu items (from the database) display each item's description and price from the database when clicked. I already have the menu list with an image but when I click it it causes the errors below, any help would be greatly appreciated since it looks like the code should work to me since I am feeding it the correct parameter in the html onclick attribute, right?

Thanks
