Trying to deploy a simple Todo list app with a Go backend and React frontend and it keeps failing

Hello,
I have a showcase with an employer soon enough here and I am trying to deploy a small in memory golang react todo application and it keeps failing after a successful build. I am not sure what the issue is here and would like some help with this.

Hey,

Make sure you’re starting your app on 0.0.0.0:10000 (or any port set in the “PORT” environment variable)

Regards.
