Description

When creating an API Product, if identical resources (e.g. GET /hello ) are selected from multiple base APIs, the backend correctly returns a 400 Bad Request response indicating a conflict.
However, in this scenario, the Publisher UI fails to handle the error state properly — Create & Publish button remains stuck in the “Creating revision” state, instead of returning back to its previous state after the error response is received.

Steps to Reproduce

1. Create two base APIs (e.g., API1 and API2) that both contain a resource GET /users/{id}.
2. Create a new API Product in the Publisher.
3. Add the same resource (GET /users/{id}) from both base APIs.
4. Click Create API Product.
