Hi elbro, can you share more information? The full HTTP URL that's failing, how to reproduce it, some code snippets if possible.

What version of firebase are you using?
HTTP 2.0 may yield better results also

Hey @elbro. We need more information to resolve this issue but there hasn't been an update in 7 weekdays. I'm marking the issue as stale and if there are no new updates in the next 3 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

Getting this again;

firebase --version: 12.4.2

npm package: "firebase": "^9.23.0"

it downloaded the latest version of the emulator .jar, but not sure how to verify this one.

project is a nextjs react app, setup;

const firestore = getFirestore(app)
connectFirestoreEmulator(firestore, 'localhost', 9100)

in console i see this request returning 426

response headers:
    HTTP/1.1 426 Upgrade Required
    Server: WebSocket++/0.8.2

how can I force HTTP 2?

firebase.json:

    "auth": {
      "port": 9099
    },
    "functions": {
      "port": 9101
    },
    "firestore": {
      "port": 9100
    },
    "ui": {
      "enabled": true,
      "port": 8000
    },
    "singleProjectMode": true
  },```

In the original report it looks like listCollectionIds is being called - is this from the Emulator UI? Or does the connectFirestoreEmulator fail immediately?

If we can reproduce the problem on our end it'll make fixing it much faster.

Hey, it's failing immediately; in console i see immediate 426 POST errors. Can't figure out why it's not connecting to the emulator - how can I troubleshoot that?

Going to the emulator ui errors immediately on the firestore page;

Completely ignoring my app, I see Access to fetch at 'http://127.0.0.1:9100/v1/projects/swg-baas/databases/(default)/documents:listCollectionIds' from origin 'http://localhost:8000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled. error visiting the emulator UI.

edit: pretty sure it's related to this firebase/firebase-tools-ui#332
