Firebase Firestore emulator does not display any data when run from WSL 2 Ubuntu

[es80]

[REQUIRED] Environment info

firebase-tools: 8.6.0

Platform: Windows WSL 2 Ubuntu (20.04)

[REQUIRED] Test case

$ cat functions/src/index.ts
import * as admin from 'firebase-admin';

admin.initializeApp()

import * as functions from 'firebase-functions';

// // Start writing Firebase Functions
// // https://firebase.google.com/docs/functions/typescript
//

export const helloWorld = functions.https.onRequest(async (request, response) => {
  functions.logger.info("Hello logs!", { structuredData: true });

  const db = admin.firestore();
  await db.collection('tests').doc('test').set({ testing: 'a test' })
  const doc = await db.collection('tests').doc('test').get()
  if (doc.exists) {
    functions.logger.log(doc.data())
  }

  response.send("Hello from Firebase!");
});

[REQUIRED] Steps to reproduce

$ firebase init

Modify functions/src/index.ts as above.

$ firebase deploy

Call function, confirm data written and read back OK via logs and firestore itself.

$ firebase emulators:start

Call function, confirm data written and read back OK via logs.
However, no data displayed in (localhost) firestore.

Now switch away from WSL 2 Ubuntu to regular Windows.

> firebase emualtors:start

Call function, confirm data written and read back OK via logs and (localhost) firestore.

[REQUIRED] Expected behavior

Data should be displayed in localhost firestore.

[REQUIRED] Actual behavior

No data displayed in localhost firestore.

$ firebase emulators:start --debug

@es80 thanks for the logs and the reproduction instructions!

@yuchenshi is this the same WSL error you've been looking into here firebase/firebase-tools-ui#332?

[yuchenshi]

It's unclear whether this is a connectivity issue or something like that. I have one request for @es80 -- could you please pull up your browser's developer tools, navigate to Network Requests and then refresh the Emulator UI page at the very end?

If things show up after refresh, then you're running into a known issue -- collections are NOT real-time in the viewer. Documents and fields are, but collections themselves will only show up after fresh.

If you see network errors, just screenshot these errors and we'll take a closer look.

[es80]

Hello. After running the function, refreshing the Firestore Emulator UI shows two network errors:

The first

The second

The first one had a request call stack, don't know if that is of any use:

[es80]

Also, I noticed that I cannot manually add a root collection. If I type a collection name in the path I can start adding documents but if I navigate back to root they no longer show. Type the path in again and I can get them back. Typing the path to the document my function added displays 'this document does not exist':

[yuchenshi]

I think you're experiencing firebase/firebase-tools-ui#332.

Navigating to a path won't create that path. To start a collection, click on the "Start collection" menu item under "Root" as shown in your last screenshot. But again, I don't think that is going to work either given the WSL issue.

Please head over to firebase/firebase-tools-ui#332 for workarounds and subscribe for updates.
