使用本地模拟器 - Firebase服务 - 错误：证书对象必须是对象

目标

使用firebase仿真器并在本地部署firebase Cloud 功能以进行测试和调试 .

问题

当 firebase serve 运行时，它失败并显示 - Error: Certificate object must be an object.

已尝试过什么

按照Google的文档here，说明包括以下步骤：

要为模拟功能（ Cloud Firestore和实时数据库除外）设置管理员凭据，请执行以下操作：打开Google Cloud Console的“服务帐户”面板 . 确保选择了App Engine默认服务帐户，并使用右侧的选项菜单选择创建密钥 . 出现提示时，为密钥类型选择JSON，然后单击“创建” . 将您的Google默认凭据设置为指向下载的密钥：$ export GOOGLE_APPLICATION_CREDENTIALS =“path / to / key.json”$ firebase functions：shell OR $ firebase serve --only functions

完成这些说明并运行 firebase serve ...失败 . 这是日志：

问题

我该如何解决这两个错误？

• 我安装了firebase-functions，并试过 npm i --save firebase-functions

⚠ functions: Failed to load functions source code. Ensure that you have the latest SDK by running npm i --save firebase-functions inside the functions directory.

• 认为这与 GOOGLE_APPLICATION_CREDENTIALS 有关，但我在这里发生了_618168 .

⚠ functions: Error from emulator. Error occurred while parsing your function triggers.

错误：证书对象必须是对象 .

更新

在文档中，它的内容如下：

如果您正在使用自定义函数配置变量，请在运行firebase serve之前在项目的functions目录中运行以下命令 . firebase函数：config：get> .runtimeconfig.json

运行此命令后，我不再收到证书错误 . 活泉！但是，我收到了新的失败，并没有多少日志提示 .

代码

这是 helloSlack 的firebase Cloud 功能

exports.helloSlack = functions.https.onRequest((req, res) => {
  if (req) {
    res.status(200).send(req.body);
  } else {
    console.log("req Error...");
    throw res.status(500);
  }
});
