git - 尝试推送到远程存储库时出现远程拒绝错误

Question

我正在尝试clone --mirror一个云源存储库并将其推送到 gitlab 作为备份机制。当我第一次尝试这样做时，没有错误。但是，当我在将一些更改推送到云源存储库后再次对其进行测试时，我收到了以下错误。

! [remote rejected] origin/feature -> origin/feature (deny updating a hidden ref)  
! [remote rejected] origin/master -> origin/master (deny updating a hidden ref)  
! [remote rejected] origin/test -> origin/test (deny updating a hidden ref) error: failed to push some refs to 'https://gitlab.com/xxxx.git'

下面是每次需要进行备份时触发的构建配置文件。

    steps:
  - name: gcr.io/cloud-builders/git
    args:
      - clone
      - '--mirror'
      - 'https://source.developers.google.com/cloud-source-repo'
  - name: gcr.io/cloud-builders/git
    args:
      - fetch
      - '--unshallow'
  - name: gcr.io/cloud-builders/git
    args:
      - '-c'
      - ls
      - cd backup-to-gitlab.git
    entrypoint: bash
  - name: gcr.io/cloud-builders/git
    args:
      - remote
      - set-url
      - '--push'
      - origin
      - >-
        https://xxx:password@gitlab.com/xxxx.git
  - name: gcr.io/cloud-builders/git
    args:
