Current Limitation: The Register Catalog step currently only supports IDP 1.0 ( backstage.io/v1alpha1 ) entities. When attempting to use IDP 2.0 ( harness.io/v1 ), the step fails because the Catalog API internally calls the convert API, which expects the older schema. Workaround: At present, users must replace the step with a Run step that directly calls the IDP 2.0 Create Entity API. This works functionally but bypasses the simplicity and governance benefits of the native pipeline step. Enhancement Request: Update the Register Catalog step to: Accept and process IDP 2.0 ( harness.io/v1 ) entities natively. Preserve backward compatibility with IDP 1.0 ( backstage.io/v1alpha1 ). Remove the need for scripting workarounds when working with IDP 2.0.
