我试图在私有仓库上使用Github Action创建git clone，但我不确定如何配置它以使用SSH连接到GitHub。顺便说一下，它是一个macOS运行器。
此时，actions/checkout工作正常，但当我直接调用git clone时，抛出了这个错误。
.yml文件如下所示：

name: Release IOS
on: 
  push:
    branches:
      - github-action
jobs:
  build:
    name: Build IPA and upload to TestFlight
    runs-on: macos-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2
        with:
          ref: ${{ github.head_ref }}
      - name: Check Github User
        run: |
          git --version
          git config user.name 'MyUsername'
          git config user.email 'MyEmail'
          git config user.name
          git config user.email
        env:
          NODE_AUTH_TOKEN: ${{ secrets.PERSONAL_ACCESS_TOKEN }}
      - name: Setup Node.js
        uses: actions/setup-node@v1
        with:
          node-version: 14.17.0
        env:
          NODE_AUTH_TOKEN: ${{ secrets.PERSONAL_ACCESS_TOKEN }}
      - name: Set up SSH
        uses: pioug/la-cle@v1.1.0
        with:
          GH_SSH_KEY: ${{ secrets.SSH_PRIVATE_KEY }}
      - name: Try copy a private repo
        run: git clone https://github.com/MyUsername/MyRepo.git
