Description

I want to use the Firestore with MongoDB as my database. I was able to read/write data on server side using firestore nodejs Admin package. But in the client side (flutter app) when i try to read data using the cloud_firestore i get this error

"W/Firestore(30072): (26.0.0) [WatchStream]: (19e0c6d) Stream closed with status: Status{code=UNAVAILABLE, description=The service is temporarily unavailable., cause=null}. W/Firestore(30072): (26.0.0) [OnlineStateTracker]: Could not reach Cloud Firestore backend. Connection failed 1 times. Most recent error: Status{code=UNAVAILABLE, description=The service is temporarily unavailable., cause=null} W/Firestore(30072): This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend."

But if i switch to a standard firestore DB then there's no error.

Reproducing the issue

I created a flutter app that uses "Firestore with MongoDB compatibility". Then i tried to read data from Firestore DB that has MongoDB compatibility.

import 'package:cloud_firestore/cloud_firestore.dart' as f;

FirebaseApp app = await Firebase.initializeApp( options: DefaultFirebaseOptions.currentPlatform, );

f.FirebaseFirestore firestore = f.FirebaseFirestore.instanceFor(app: app, databaseId: 'mongodb');

Firebase Core version

^4.1.0

Flutter Version
