这个 arrayUnion 方法在 https 云函数中失败了什么？

Question

预期行为

在 https.onCall 云函数中调用 admin.firestore.FieldValue 方法时，我们的 Cloud Firestore 数据库中的目标文档会更新为新数据。

观察到的行为

每次调用都会产生此错误：

Unhandled error TypeError: Class constructor FieldValue cannot be invoked without 'new'
    at /workspace/dist/index.js:2245:38
    at Generator.next (<anonymous>)
    at asyncGeneratorStep (/workspace/dist/index.js:19:103)
    at _next (/workspace/dist/index.js:21:194)

    at func (/workspace/node_modules/firebase-functions/lib/providers/https.js:273:32)
    at process._tickCallback (internal/process/next_tick.js:68:7)

代码示例

这是我通过 Firebase 编写和部署的 Cloud Function：

exports.recordReferralRegistration = functions.https.onCall(async ({ arguments }) => {
    // why is this not working?
    // adds the value to a document
    .firestore()
    .collection("users")
    .doc(xyz)
    .update({
      activityCodes: admin.firestore.FieldValue(dataToAdd),
    })

    return 'success'
  }
)

过去的研究

它这可能是 Babel 和 ES5/6 转译的问题。
有趣的是，我的编码合作伙伴使用完全相同的语法似乎没有这个问题，我们正在使用完全相同的 .babelrc 设置进行构建。

{
  "presets": [
    [
      "@babel/preset-env",
      {
        "targets": {
          "node": "10"
        }
      }
    ],
    "@babel/preset-react"
  ]
}

Answer 1

数组并集的正确语法是：

admin.firestore.FieldValue.arrayUnion(dataToAdd)

您的代码中缺少 .arrayUnion。

另请参阅 adding elements to an array 上的 Firebase 文档。
