The NodeJS program running result is different in Github Action SSH Remote Commands

[hh54188]

In a NodeJS program I use the ES module by specifying the type field inside the project. Also I created an ecosystem.config.js for PM2 usage purposes. But because the PM2 still using the CommonJS module, I gave it a cjs suffix

This is the ecosystem.config.js content:

module.exports = {
    apps: [{
        name: "app-name",
        script: "./index.mjs",
    }]
}

This is the folder structure:

project-root/
├── node_modules/         
├── .env                 
├── .gitignore          
├── ecosystem.config.cjs 
├── index.mjs           
└── package.json        

And I deploy the project to the DigitalOcean Droplet via Github Action SSH Remote Commands

  - name: SSH Remote Commands
    uses: appleboy/[email protected]
    with:
      host: xxx.xxx.xxx.xxx
      username: root
      key: ${{ secrets.SSH_KEY }}
      script: |
        pm2 stop ${{ env.REPO_NAME }}
        pm2 flush ${{ env.REPO_NAME }}
        pm2 start ecosystem.config.cjs
        exit

After deployment I got this error:

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /root/nodejs-app/index.mjs
    at Module.load (internal/modules/cjs/loader.js:861:11)

    at internal/main/run_main_module.js:17:47 {
  code: 'ERR_REQUIRE_ESM'
}

However, if I manually run the PM2 command in the VPS by myself everything would be fine. What’s wrong with the Github Action
