App Engine Studio: “Scope already taken by another app” error

[dareamb]

Hey everyone,

I’m working in my ServiceNow developer instance and keep running into this error whenever I try to create a new app in App Engine Studio (AES):

"Unable to create this application. Go back to the create app experience and enter a different scope name. Details: Failed to create templated object. Details: This scope is already taken by another application." (Screenshots are attached)

Here’s what I’ve tried so far:
- Verified that I have full admin privileges (I can access System Properties → My Company, Studio, sys_scope.list, etc.)
- Checked sys_scope.list and sys_app.list — there are no apps or scopes named “Hello Daream”
- Tried new names like “Hello Daream v2” and “MyFirstDareamApp001”
- Cleared cache, switched browsers
- Confirmed it’s not a permissions issue

Even though I get to the “Add Roles” screen, AES still throws the same scope error after clicking Continue.

Has anyone seen this before? Could my App Engine Studio metadata or scope registry be stuck? Is there a way to reset or re-register scopes in a dev instance?

Thanks in advance for any help!
