Firebase Emulator UI requires a project ID to start

Question

I have run through the docs and can not get the UI firebase emulator to work.

I'm using firebase version: 9.22.0 on a mac M1

warning in console.

i  emulators: Starting emulators: hosting
i  hosting: Serving hosting files from: build
✔  hosting: Local server: http://localhost:5001
⚠  emulators: The Emulator UI requires a project ID to start. Configure your default project with 'firebase use' or pass the --project flag.

┌─────────────────────────────────────────────────────────────┐
│ ✔  All emulators ready! It is now safe to connect your app. │
└─────────────────────────────────────────────────────────────┘

┌──────────┬────────────────┐
│ Emulator │ Host:Port      │
├──────────┼────────────────┤
│ Hosting  │ localhost:5001 │
└──────────┴────────────────┘
  Emulator Hub running at localhost:4400
  Other reserved ports: None

I have tried using the --project myproject and it still does not work.

Firebase.json

{
  "hosting": {
    "public": "build",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [
      {
        "source": "**",
        "destination": "/index.html"
      }
    ]
  },
  "emulators": {
    "hosting": {
      "port": 5001
    },
    "ui": {
      "enabled": true,
      "host": "localhost",
      "port": 4000
    }
  }
}

I've made sure my emulators are setup: firebase init emulators

Can anyone help this is driving me crazy.

I ran into this same issue. I don't exactly know what all steps it took to be resolved, as it took a few attempts to get it working for me. I ended up doing the following to resolve it

Update Firebase-Tools to latest version npm i -g firebase-tools (I was originally running v9.9.0)
Delete my firebase.json and .firebaserc files. Run firebase init again to set up the project
Run into an error when trying to start emulator documented here https://github.com/Automattic/cli-table/issues/153
Manually edit firebase-tools/package.json file and change the "cli-table": "https://github.com/phess101/cli-table.git" dependency.
Install globally installed firebase-tools dependencies using npm install
Run the emulator again

I submitted a pull request to the cli-table project, hopefully it can be reviewed and released soon. Looks like they just recently did a release and broke that portion of the firebase-tools code https://github.com/Automattic/cli-table/pull/154
