javascript - firebase firestore 和 grpc 中未建立连接错误

Question

它是一个函数，如果不存在则通过引用现有数据来添加新数据，如果存在则更新数据。它运行良好，但一个小时后gRpc发生错误。详情如下:

Error: No connection established at Http2CallStream.<anonymous> (D:\zyleTcpServer\node_modules\@grpc\grpc-js\build\src\call.js:68:41) at Http2CallStream.emit (events.js:215:7) at D:\zyleTcpServer\node_modules\@grpc\grpc-js\build\src\call-stream.js:75:22 at processTicksAndRejections (internal/process/task_queues.js:75:11) --------------------------------------------- at BunWrapper.Readable.on (D:\zyleTcpServer\node_modules\bun\node_modules\readable-stream\lib\_stream_readable.js:729:33) at D:\zyleTcpServer\node_modules\@google-cloud\firestore\build\src\index.js:920:26 at new Promise (<anonymous>) at Firestore._initializeStream (D:\zyleTcpServer\node_modules\@google-cloud\firestore\build\src\index.js:881:16) at D:\zyleTcpServer\node_modules\@google-cloud\firestore\build\src\index.js:1017:28 { code: 14, details: 'No connection established', metadata: Metadata { internalRepr: Map {}, options: {} } }
这是我的代码

<code>
    const docName = `${vin}-${dtc}`; //make doc
    const ebsRef = db.collection('events').doc(docName);
    await db.runTransaction((t) => t.get(ebsRef)
      .then(async (doc) => {
        if (!doc.exists) {
          return t.set({
           startDatetime: firebase.firestore.FieldValue.serverTimestamp(),
           endDatetime: firebase.firestore.FieldValue.serverTimestamp(),
           description: dtcData.description,
           dtcCode: dtc,
           eventType: brokenType,
           scannerCode: dtcData.scanner,
           vin,
          });
       }
       return t.update(ebsRef, {
         status: (rawDtc.status === '08' ? 2 : 1),
         endDatetime: firebase.firestore.FieldValue.serverTimestamp(),
      });
    </code>

我的源代码有问题吗？ 我该如何解决...？

Answer 1

Other people reported to be having the same issue in the past week, as mentioned on Firebase Functions Github. This occurs to every kind of function that involves firestore and it's related to firestore changing grpc to grpc-js. As mentioned in the conversation thread, there are some workarounds that you can try:

解决方法

1 - Updating from "firebase-functions": "^3.2.0" to "firebase-functions": "^3.3.0"

或

2 - Deleting your /src/functions/node_modules and /src/functions/package-lock.json, updating your dependencies, and pushing your changes that include your new dependencies in your /src/functions/package.json to your firebase app.

---

最后，你的依赖应该是:

@grpc/grpc-js": "0.6.9"

这个对话线程 grpc/grpc-node#1027还解释了更新您的部门的方法，这也很有帮助。
