我正在尝试按照本指南在 Google Compute Engine 中设置 Node 项目：https ://cloud.google.com/nodejs/getting-started/getting-started-on-compute-engine
在启动脚本上一切正常，直到第 27 行：
git clone https://source.developers.google.com/p/${PROJECTID}/r/${REPOSITORY} /opt/app/new-repo
当脚本尝试克隆 repo 时，我在日志中收到一些错误：
INVALID_ARGUMENT: Request contains an invalid argument
message: "Invalid authentication credentials. Please generate a new identifier: https://source.developers.google.com/new-password"
fatal: unable to access 'https://source.developers.google.com/<path-to-repo>': The requested URL returned error: 400
此错误的原因可能是什么，我该如何解决？我试图研究克隆身份验证，但没有找到与脚本相关的任何内容。我访问了新密码链接，并尝试在服务器中执行 gitcookie 命令，但没有帮助。
我使用的启动脚本与指南中的完全一样：
set -v

PROJECTID=$(curl -s "http://metadata.google.internal/computeMetadata/v1/project/project-id" -H "Metadata-Flavor: Google")
