The Backstage application deployment failed for both the `showcase` and `showcase-rbac` projects, preventing the E2E tests from running. The application pods for both projects entered a `CrashLoopBackOff` state. The logs for the `install-dynamic-plugins` init container reveal a fatal error during the plugin installation process: `InstallException: Cannot use inherit for oci://registry.access.redhat.com/rhdh/red-hat-developer-hub-backstage-plugin-scaffolder-backend-module-orchestrator: no existing plugin configuration found. Ensure a plugin from this image is defined in an included file with an explicit version.` The root cause is a misconfiguration in the dynamic plugin installation script where an `inherit` directive is used for a plugin without a corresponding base configuration.
