想知道是否有人可以帮助解决以下错误我正在尝试运行GOCD管道。
Go服务器安装在Mac mini上，我在Windows机器上运行Go Agent。
我安装了Source Tree和Git for Windows。使用Source Tree或Git Bash，我可以正常运行Git而不会出现任何问题。
然而，当Go Agent尝试运行管道时，我收到以下错误

我缺乏想法，所以任何帮助都会受到赞赏。
进度更新
我已为Go Agents沙箱设置完全控制权限，但我没有收到以下错误

取消此作业，因为它没有生成超过20分钟的任何控制台输出
Git Bash目录有一个/ tmp文件夹，所以我不确定这是什么意思。
再次感谢任何帮助。
