[samtstern]

[REQUIRED] Environment info

Platform: macOS

[REQUIRED] Test case

Run firebase init and defer project selection:

? Which Firebase CLI features do you want to set up for this folder? Press Sp
ace to select features, then Enter to confirm your choices. Database: Configu
re Firebase Realtime Database and deploy rules

=== Project Setup

First, let's associate this project directory with a Firebase project.
You can create multiple project aliases by running firebase use --add,
but for now we'll just set up a default project.

? Please select an option: Don't set up a default project

=== Database Setup
i  database: ensuring required API firebasedatabase.googleapis.com is enabled...

Error: HTTP Error: 403, The caller does not have permission

[REQUIRED] Steps to reproduce

See above

[REQUIRED] Expected behavior

The firebase int flow should skip API enablement when there is no project ID and just set up local default rules/config.

[REQUIRED] Actual behavior

Fails with a 403 error.
