This problem is related to **serverless offline**.

This error occurs when deploying my aplication in local with serverless offline, and calling an endpoint with an input produce a controlled error. When this error is captured a response with statuscode 400 is returned and received. Finally an error is showed and execution is stopped. The request is returning the rigth response, but I need serverless offline to stay alive.

**This is the received response**

```auto
{"success":false,"error":"Field not found","stacktrace":"Error: Field not found\n at getField (webpack-internal:///./src/service/FieldService.ts:46:23)\n at processTicksAndRejections (internal/process/task_queues.js:97:5)"}

```

**This is the console output when the execution stops.**
