Context:

I mistakenly misspelled my login route as /dev/loginn instead of /dev/login on Postman, here is the response

{
    "currentRoute": "post - /dev/loginn",
    "error": "Serverless-offline: route not found.",
    "existingRoutes": [...],
    "statusCode": 404
}

Problem

The above response has 2 major issues

1. Existing routes are getting exposed which shouldn't be (ideally).
2. The response is too detailed. We need to keep it simple.

Fix

Add a new Lambda function to handle unmatched/ unconfigured Routes in serverless.yml

#serverless.yml

functions:
  unmatchedRoute:
    handler: handler.unmatchedRoute
    events:
      - http:
          path: /{proxy+}
          method: ANY

// handler.ts

import { Handler } from 'aws-lambda';

export const unmatchedRoute: Handler = async () => {
  return {
    statusCode: 404,
    body: '404 page not found',
  };
};
