scaffolder plugins that have not updated to the latest scaffolder-node package (0.12.0) can cause the RHDH backend to fail to start, the log file will contain a message like: {code} Plugin 'scaffolder' threw an error during startup, waiting for 14 other plugins to finish before shutting down the process. TypeError: Cannot read properties of undefined (reading 'id')     at BackendInitializer.cjs.js:262:72 {code} This is occurs when a scaffolder backend module has not been updated and is still accessing the scaffolder extension point from the "alpha" export, which was removed in scaffolder-node version 0.12.0. To remedy the problem, ensure all scaffolder modules support backstage 1.45.x and that scaffolder modules have been updated to at least scaffolder-node version 0.12.0.
