ios - 使用 firebase-tools 删除 Firestore 文档不起作用

Question

我正在从 iOS 调用云函数来删除 Firestore 中的文档。该函数被调用并执行，但实际删除从未发生。知道我做错了什么吗？

云函数:

const functions = require('firebase-functions');
const firebase_tools = require('firebase-tools');

exports.recursiveDelete = functions
  .runWith({
    timeoutSeconds: 540,
    memory: '2GB'
  })
  .https.onCall((data, context) => {
    const path = data.path;
    console.log(
      `User ${context.auth.uid} has requested to delete path ${path}`
    );

    return firebase_tools.firestore
      .delete(path, {
        project: process.env.GOOGLE_CLOUD_PROJECT,
        recursive: true,
        yes: true,
        token: functions.config().fb.token
      })
      .then(() => {
        return {
          path: path
        };
      });
  });

iOS

let deleteFunction = functions.httpsCallable("recursiveDelete")
        deleteFunction.call(["path": docPath]) { (result, error) in
            if let error = error as NSError? {
                if error.domain == FunctionsErrorDomain {
                    let code = FunctionsErrorCode(rawValue: error.code)
                    let message = error.localizedDescription
                    let details = error.userInfo[FunctionsErrorDetailsKey]
                    print("\(code): \(message)\n\nDetails: \(details)")
                }
            } else {
                print("Deletion was successful")
            }
        }

这是 Xcode 的控制台输出:

Optional(__C.FIRFunctionsErrorCode): INTERNAL

Details: nil

这是执行的日志:

尝试检查 NodeJS 的版本。在 NodeJS 10 及更高版本中，删除了许多环境变量，包括 process.env.GOOGLE_CLOUD_PROJECT ，现在返回 undefined .
而不是 process.env.GOOGLE_CLOUD_PROJECT ，您有多种选择:
将您的项目 ID 硬编码为字符串:

.delete(path, {
        project: "myprojectid-12345",
        recursive: true,
        yes: true,
        token: functions.config().fb.token
      })

您还可以从 firebase 配置中获取您的项目 ID: myProjectID = JSON.parse(process.env.FIREBASE_CONFIG).projectId请注意，如前所述 here :

FIREBASE_CONFIG is always populated by the Firebase CLI whendeploying, but will not be present when deploying via gcloud or othermeans.

或基于 this documentation在部署您的函数时设置您自己的环境变量。
