 The Server Middleware comes with a default error handler that logs errors to the console and sends a generic error response to the client. You can customize this behavior by providing your own error handler function in the `middleware.config.ts` file:
 
 ```typescript
+import type { Integration } from "@vue-storefront/middleware";
+import type { MiddlewareConfig } from "@vsf-enterprise/sapcc-api";
+
 export default {
   integrations: {
     sapcc: {
