我需要在一个分支中构建一些文件，然后使用github操作将新形成和更新的文件推到同一个存储库的另一个分支。我已经尝试过这种方法，但在commit to staging branch时总是失败

name: Deployment

on:
  push:
    branches: [ develop ]
  pull_request:
    branches: [ develop ]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - name: Build files and folders
      run: |
        ./build.sh
        rm -rf cache
        mkdir logs
        cd logs
        ls>output.txt
    - name: commit to staging 
      run: |
        git checkout staging
        git add *
        git commit -m "new push to staging"
        git push

错误
