# New validation details for activations

If validation fails when activating an EdgeWorker version, details about the error are now provided in the UI.

When creating the first version of a new EdgeWorker ID, you can now see the default [configuration options](doc:manage-edgeworkers##code-bundle-configuration-settings)  when you open the `bundle.json` file in the [Code bundle editor](doc:code-bundle-editor).
