I am using lambda integration. Returning the success response works fine. Returning error is received as success in client.
I tried using `callback(new Error('[404] Not found'));` , `callback(null, { statusCode: 404, body: 'Not found', headers: { 'Content-Type': 'text/plain' } });` , tried with custom status code too but no luck. 

Here is sample yml for helloworld function:

helloworld:
  handler: helloWorld/handler.hello
  timeout: 15
  events:
    - http:
        path: hello/worlds
        method: get
        integration: lambda
        request:
            template:
              application/json: "${file(helloWorld/test.vtl)}"
        response:
            headers:
              Access-Control-Allow-Origin: "'*'"
              Content-Type: "'application/json'"
            template: $input.path('$.errorMessage')
        cors:
            origin: '*'
            headers:
              - Content-Type
              - X-Amz-Date
              - Authorization
              - X-Api-Key
              - X-Amz-Security-Token
              - X-Amz-User-Agent
              - Startlower
              - Text
              - Access-Control-Allow-Headers
              - Access-Control-Allow-Origin
            allowCredentials: false
        authorizer:
            name: ftAuth
            type: request
  package:
    include: # Specify the directories and files which should be included in the deployment package for this specific function.
      - helloWorld/**

I almost always use the proxy integration so I’m not fully prepared for this.  
Before using serverless I fallowed this guide:
