Firebase Cloud Functions Shell 未在实时数据库上执行写操作

Question

由于几天以来我无法再在本地测试云功能，因为所有写入功能都没有执行并且没有任何返回，因此该功能挂起并最终因超时而停止。

示例函数：

import { database as dbEvent } from "firebase-functions";

export default dbEvent.ref("/tariffs/removeHistory").onCreate((event: any) => {
  console.log("START");
  const bikesHistoryRef = event.data.adminRef.parent.parent.child("bikesHistory");
  return bikesHistoryRef.set(null).then((res) => console.log("Delete done", res));
});

结果：

firebase > removeBikeHistory("test")
'Successfully invoked function.'
firebase > info: User function triggered, starting execution
info: START

firebase > 
firebase > info: Execution took 61023 ms, finished with status: 'timeout'
info: Execution took 49694 ms, finished with status: 'crash'

有什么建议吗？我的所有云功能都会出现这种情况，当我部署它们时，它就可以工作。

我试过了：

firebase-admin@5.5.1
firebase-functions@0.7.3
firebase-tools@3.15.4 (-g)

和

firebase-admin@5.6.0
firebase-functions@0.7.5
firebase-tools@3.16.0 (-g)

编辑：

启用日志记录后，我收到以下错误：

info: 0: onDisconnectEvents 
info: p:0: Making a connection attempt 
info: p:0: Failed to get token: Error: Credential implementation provided to initializeApp() via the "credential" property failed to fetch a valid Google OAuth2 access token with the following error: "Error fetching access token: invalid_grant (Bad Request)". There are two likely causes: (1) your server time is not properly synced or (2) your certificate key file has been revoked. To solve (1), re-sync the time on your server. To solve (2), make sure the key ID for your key file is still present at https://console.firebase.google.com/iam-admin/serviceaccounts/project. If not, generate a new key file at https://console.firebase.google.com/project/_/settings/serviceaccounts/adminsdk. 
p:0: data client disconnected

我在安装较旧的 firebase-function/admin 版本时确实看到了此错误，但我认为通过安装较新版本可以解决此问题。我该如何解决？

我在这个错误报告中找到了解决方案： https://github.com/firebase/firebase-functions/issues/135

我已删除以下文件，现在我的云功能再次在本地工作：

rm ~/.config/gcloud/application_default_credentials.json
