Azure web app nestjs cannot use shell scripts as startup command

Question

I have a simple nestjs application deployed in azure web app. I also have a simple shell script that does the following:

---

# !/bin/sh

npm ci
node main.js

---

I am using github actions to build the nestjs project and copy package.json, package-lock.json and other files and deploy them to azure.
github actions:

---

name: Build and deploy Nest.js app to Azure Web App

on:
push:
branches:

• dev
  workflow_dispatch:

jobs:
build:
runs-on: ubuntu-latest

steps:  
  - uses: actions/checkout@master  

  - name: Set up Node.js version  
    uses: actions/setup-node@v1  
    with:  
      node-version: "16.x"  

  - name: npm install, build, and test  
    uses: actions/setup-node@v1  
    with:  
      node-version: "16.x"  
      cache: 'npm'  
  - run: npm ci  
  - run: npm run build --if-present  
  - run: npm run test --if-present  

  - name: copy package.json and package-lock.json  
    uses: actions/setup-node@v1  
  - run: cp ./package.json ./dist/  
  - run: cp ./package-lock.json ./dist/  
  - run: cp ./deploy.sh ./dist/    
  - run: cd ./dist/ && ls  

  - name: Zip all files for upload between jobs  
    run: zip --symlinks -r nest.zip ./dist/*  

  - name: Upload artifact for deployment job  
    uses: actions/upload-artifact@v2  
    with:  
      name: ${{ secrets.DEV_AZURE_APP_API_NAME }}  
      path: nest.zip  

  - name: 'Deploy to Azure Web App'  
    id: deploy-to-webapp  
    uses: azure/webapps-deploy@v2  
    with:  
      app-name: ${{ secrets.DEV_AZURE_APP_API_NAME }}  
      publish-profile: ${{ secrets.DEV_AZURE_PUBLISH_PROFILE_API }}  
      package: nest.zip  

  - name: Delete zip file  
    run: rm nest.zip  

---

my startup command: ./dist/deploy.sh

The issue I see is that deploy.sh file copied from github actions is not available after being unzipped by azure web apps.

The reason for going for a shell script for nestjs is because zipping node_modules causes our deployment to take around 10 minutes because our zip file is about 70mb in size.
