      $changes = git diff --name-only --relative --diff-filter AMR $last_tag HEAD .
      if ($changes -is [string]){ 
        echo "Nothing changed $changes" }
      else
      {
          if ($changes -is [array])
          {       
              foreach ($change in $changes){
                 if ($change -like '*Azure.Infra/SecOpsTest/*') {

                }
          }

在 docker 容器中

3b0d28970e58        docker.software-univention.de/zammad-zammad-nginx:3.6.0-42           "/docker-entrypoint.…"   24 minutes ago      Up 3 minutes        0.0.0.0:40001->80/tcp   zammad_zammad-nginx_1

有谁知道这里出了什么问题？操作系统是最新的 UCS 4（基于 Debian）。

最好的问候，
