Creating multiple components with same label causes error: entity with ID already exists

Created on 19 March 2025, 15 days ago

When I attempt to create a component with a name as one that already exists, it tries to use the same machine name (ID), and I get an error.:

{
    "status": 409,
    "data": {
        "errors": [
            "'js_component' entity with ID 'image' already exists."
        ]
    }
}

There are 2 different ways to trigger this error:

Standard components:

Create a "Hero" component.
Create another "Hero" component with the same name ("Hero").
Try to create a third "Hero" component with the same name and you will get the error.

Dynamic components:

Create a component with the same name as a dynamic component, e.g., 'breadcrumb'.
Try to create another component with same name and you will get the error.

The API response already is a 409, which conveys "conflict". That happened in 🐛 ApiConfigControllers::post() should detect a conflicting ID and throw a 409 exception Active , to address @balintbrews' #3503547-2: Display validation errors in dialogs that create XB config entities (code component, section) → .

This is a subset of 📌 Add (validation) error handling to AddCodeComponentDialog and friends Active . I'm tempted to mark this a duplicate, but actually, this probably deserves its own UX, so keeping it separate makes sense?
