Error on deploy using Back4App

[manm15]

2023-03-16T15:19:39.291Z # trying to hit the 8080 port using http

2023-03-16T15:19:42.376Z # it looks that no process is listening to the 8080 port using http

2023-03-16T15:19:42.377Z # app did not turn healthy after several checks

2023-03-16T15:19:42.378Z # deployment failed

Does anyone know how I can fix it?

It may be because you have not provided the API_KEYS environment variable

[manm15]

I have done the API keys but it is the Port's problem. And I also cannot run with Render.com.

The port should be 8080 by default, as specified in the 7th line of the source code.
