[REQUIRED] Environment info

firebase-tools: 9.18.0

Platform: Ubuntu

[REQUIRED] Steps to reproduce

React project builds to the build folder, run firebase emulators:start --only hosting

[REQUIRED] Expected behavior

Should run the emulator and be visible in the Emultor-UI

[REQUIRED] Actual behavior

Does not run the Emulator-UI and displays the following warning:

⚠  emulators: The Emulator UI requires a project ID to start. Configure your default project with 'firebase use' or pass the --project flag.

The suggestions do not fix the problem, I have .firebaserc and even when setting --project my-project-id it does not work, nor with GCLOUD_PROJECT=my-project-id system variable
