I am following a guide on how to deploy an app:
https://github.com/GoogleCloudPlatform/genai-for-marketing/tree/main?tab=readme-ov-file

I have a functioning frontend, ie. I can access the firebase deployed app and have click functionalities, etc. The issue comes when I try to do anything related to the backend. When I try to use Post/Get via postman for example, I get 500 Internal Server Error.

Please note that I am not a software engineer. If any more information is needed, please ask and I will provide.

I have followed the HowTo to deploy the app, expected it to work, but it doesn’t.
