Github actions to deploy subdirectory flask project to Azure Web App

Question

I have this folder structure:

It is a react web app, with backend folders included like flask and nodejs.

Due to requirements I'm required to combine my backend towards my frontend code.

Hence I've tried several ways and modifying my github actions file and finally managed to got it to working.

This is my yml file.

As i just want to deploy my backend-flask/ folder to a azure web app, it takes a pretty long time.

Is waiting up to 22min normal?

My issue is almost the same as similar problem

I've tried using the solution by adding package name to backend-flask/ but

Else does my .yml have a problem?

After 40minutes it finally failed:
