Back End Development and APIs Projects - Exercise Tracker

Tell us what’s happening:
My code for the exercise tracker project works fine when I test it on repl, but when I submit it on the website, all the test cases say they timeout. I checked the console output, and there are some errors about CORS, but I am using the cors module and that should enable cors. I am not sure what to do about this, so any help would be greatly appreciated. Thanks in advance!

Your code so far

Here’s the link to my repl: boilerplate-project-exercisetracker - Nix (beta) Repl - Replit
