谷歌云功能GitHub auto-deployer说：请求有错误

Question

我已经为Google Cloud Functions安装了GitHub auto-deployer，但是当我现在将我的功能推送到我的GitHub存储库时，我收到一个抽象的错误消息"The request has errors"，其中包含以下非描述性细节。什么可能在这里特别出错？

更新在堆栈跟踪中提到google-auth-library让我觉得我的凭据可能有问题。但gcloud auth list的输出似乎没问题：

Credentialed Accounts
ACTIVE  ACCOUNT
*       [MY_ID]@gmail.com

更新可能有些不同寻常的是我在我的"path":"",有config.json。但是后来我的index.js直接驻留在我的存储库的顶部，所以没有指定的路径。

更新This是githubAutoDeployer传递Google Cloud Functions的错误（遗憾的是，上游服务器的源代码显然不可用）：

gcf.projects.locations.functions.create({ resource, location }, (err, operation) => {
  if (err && err.errors && err.errors[0] && err.errors[0].reason === 'alreadyExists') {
    // ...
  } else if (err) {
    console.error(`Failed to create function ${resource.name}`, err);
    reject(err);
  }

问题是我在我的"location" : "us-central"中指定us-central1而不是supports Google Cloud Functions（config.json）。

我发现了一个原始的POST请求到Google Cloud Functions API（在获得服务帐户和访问令牌等之后）。在此级别，API返回明确的错误指示：

"fieldViolations": [
  {
    "field": "region",
    "description": "region us-central is not supported."
  }
]

显然，不幸的是，当githubAutoDeployer尝试同一个呼叫时，这不会输入任何日志文件。
