Github workflow action timeout error, continues log streamed to console

What's going wrong?

Executing pm2 restart --no-daemon using ssh from github action caused continues log stream and github action exits with Run Command Timeout! error.

How could we reproduce this issue?

I have simple GitHub action that connects to the server using ssh. I'm running the pm2 restart --no-daemon from github action and it ends up with continuous pm2 logs stream causing timeout from github action itself.

Supporting information

Here is the workflow action for deployment

name: Continuous Integration Custimonial Production

on:
  push:
    branches: [master]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Deploy NodeJS app
        uses: appleboy/ssh-action@v0.1.2
        with:
          host: ${{secrets.SSH_HOST}}
          key: ${{secrets.SSH_KEY}}
          username: ${{ secrets.SSH_USER }}

          script: |
            cd ~/demo/demo
            git pull
            npm install --production
            pm2 kill demo
            NODE_ENV=production && pm2 start ecosystem.config.json --no-daemon
            echo 'Deployment successful to digital ocean'

Here is the ecosystem config file

{
  "apps": [
    {
      "name": "demo",
      "script": "src/index.js",
      "instances": 1,
      "autorestart": true,
      "watch": false,
      "time": true,
      "env": {
        "NODE_ENV": "production"
      }
    }
  ]
}

This is the error log at the end of github action log

err: Run Command Timeout!
2021/09/09 08:51:03 Error: command timeout

Start with the provided GitHub Actions deployment workflow and ecosystem.config.json, reproducing the remote pm2 restart/start command through appleboy/ssh-action. Compare the command's log behavior with the action's timeout; done means the deployment command exits and the workflow reaches its success message without a continuous log stream.
