however the API works perfectly fine locally on the development environment. any clues on what is causing this problem.
it seems that the problem was a typo. I'm using Windows for local development which is path case insensitive. but the production environment is Linux which is a case sensitive and that what was causing the problem since I was trying to import the module from Models directory where it was named models
