-use `fromConfig` for all scaffolder helpers, and use the url protocol for app-config location entries
+use `fromConfig` for all scaffolder helpers, and use the url protocol for app-config location entries.
+
+To apply this change to your local installation, replace the contents of your `packages/backend/src/plugins/scaffolder.ts` with the following contents:
+
+```ts
+import {
+  CookieCutter,
+  createRouter,
+  Preparers,
+  Publishers,
+  CreateReactAppTemplater,
+  Templaters,
+  CatalogEntityClient,
+} from '@backstage/plugin-scaffolder-backend';
+import { SingleHostDiscovery } from '@backstage/backend-common';
+import type { PluginEnvironment } from '../types';
+import Docker from 'dockerode';
+
+export default async function createPlugin({
+  logger,
+  config,
+}: PluginEnvironment) {
+  const cookiecutterTemplater = new CookieCutter();
+  const craTemplater = new CreateReactAppTemplater();
+  const templaters = new Templaters();
+  templaters.register('cookiecutter', cookiecutterTemplater);
+  templaters.register('cra', craTemplater);
+
+  const preparers = await Preparers.fromConfig(config, { logger });
+  const publishers = await Publishers.fromConfig(config, { logger });
+
+  const dockerClient = new Docker();
+
+  const discovery = SingleHostDiscovery.fromConfig(config);
+  const entityClient = new CatalogEntityClient({ discovery });
+
+  return await createRouter({
+    preparers,
+    templaters,
+    publishers,
+    logger,
+    config,
+    dockerClient,
+    entityClient,
+  });
+}
+```
+
+This will ensure that the `scaffolder-backend` backage can add handlers for the `url` protocol which is becoming the standard when registering entities in the `catalog`
