i’m looking for ways to return error messages on the API with lambda integration (not lambda-proxy integration) and want to eliminate `errorStackTrace` when using:

`callback(new Error('[400] Something is wrong here'))`

and want to return something like the response below and get a `400 Bad Request` header in Postman:

```auto
{
   message: "Something is wrong here"
}

```

How do you guys do it?

Have you tried adding a response template for the 400 status code? [https://serverless.com/framework/docs/providers/aws/events/apigateway/#responses](https://serverless.com/framework/docs/providers/aws/events/apigateway/#responses)
