firebase-admin-node: Firestore Realtime listener drops a connection and does not reconnect

• Operating System version: Nodejs (Alpine based) docker container, node:8.7.0-alpine
• Firebase SDK version: 5.4.2
• Library version: @google-cloud/firestore 0.8.2
• Firebase Product: Firestore

We have a simple Firestore Realtime listener running on Docker container at Google Container Engine. Few times, listener for some reason have lost a connection and does not reconnect. Updates (sets, updates and deletes) does work but we don’t get notifications of updates, until we restart a container.

Error message we have got couple of times during last week:

Error: Error: Endpoint read failed
    at sendError (/usr/src/app/node_modules/@google-cloud/firestore/src/watch.js:254:15)

Once (first time) we have got this:

Error: Error: Transport closed
    at sendError (/usr/src/app/node_modules/@google-cloud/firestore/src/watch.js:254:15)
    at maybeReopenStream (/usr/src/app/node_modules/@google-cloud/firestore/src/watch.js:268:9)

    at ClientDuplexStream.<anonymous> (/usr/src/app/node_modules/google-gax/lib/streaming.js:130:17)
    at emitOne (events.js:115:13)

Our code is basically like this:

 var admin = require("firebase-admin");
  var serviceAccount = require("./credentials.json");
  
  admin.initializeApp({
    credential: admin.credential.cert(serviceAccount),
    databaseURL: "https://xxxxxxxx.firebaseio.com"
  });
  var db = admin.firestore();
  
  db.collection("demodata").onSnapshot(querySnapshot => {
    querySnapshot.forEach(doc => {
      //.. doing stuff with data
      console.log(doc.data());
    });
  });

Is listener planned to survive on these situations, or should be build some kind retry system by ourselves?

Thanks!
