Auto deploy github with action throug ssh return rsync exited with code 255

Question

I want to deploy my NodeJS GitHub project to my VPs using ssh, so I make this script in .github/workflows :

  
name: Node CI

on: [push]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v1
    - name: Install Node.js
      uses: actions/setup-node@v1
      with:
        node-version: '10.x'
    - name: Install npm dependencies
      run: npm install
    - name: Run build task
      run: npm run build --if-present
    - name: Deploy to Server
      uses: easingthemes/ssh-deploy@v2.2.11
      env:
          SSH_PRIVATE_KEY: ${{ secrets.SSH_KEY }}
          ARGS: "-rltgoDzvO --delete"
          SOURCE: "/"
          REMOTE_HOST: ${{ secrets.HOST }}
          REMOTE_USER: ${{ secrets.USERNAME }}
          TARGET: ${{ secrets.FOLDER_TARGET }}
          EXCLUDE: "/dist/, /node_modules/"

I enter every information in my secret repository key. And to generate the ssh key, I'm using this command : ssh-keygen -m PEM -t rsa -b 4096 with not paraphrase. And I have passed the ~/.ssh/id_rsa` string inside SSH_KEY value

But after all of that, I have this error when run the action script:

Answer 1

Check first that, as mentioned in easingthemes/ssh-deploy README, the public key part has been added to the authorized_keys file on the server that receives the deployment.

Try and test it with

ssh -Tv -i /home/runner/.ssh/deploy_key -o StrictHostKeyChecking=no $REMOTE_USER@$REMOTE_HOST

The OP MrSolarius adds in the comments:

I have use my private key instead of my public key, so now it works.
