The Problem:

When creating a new application in ServiceNow, you might encounter the following error:

"Your app encountered an unexpected error while being created. Details: Failed to create templated object, details: This scope is already taken by another application."

The Reason

This error indicates that the application scope you've chosen is already in use within your instance. In ServiceNow, each application must have a unique scope to prevent conflicts and ensure proper isolation of components.

Solutions

1. Use ServiceNow Studio or Creator Studio:

• These tools allow you to specify and modify the application scope during creation.
• Ensure the scope identifier you choose is unique within your instance. See next section.

2. Check Existing Application Scopes:

• Navigate to the list of scoped applications by typing sys_scope.list in the application navigator and pressing Enter.
• Review the list to see if the desired scope already exists.

3. Choose a Unique Scope Identifier:

• If a conflict exists, modify the application name or manually set a distinct scope identifier to ensure uniqueness.
