Jackson databind 2.6.7.1 jar не будет анализировать мой JSON в POJO с помощью AWS Lambda Gateway

Я пытаюсь отладить, почему мой входной json в AWS Lambda GateAPI не анализирует тело JSON. Чтобы развернуть несколько раз, шаблон CloudFormation на AWS, а затем отладить, я настроил AWS SAM на локальном компьютере для эмуляции среды без сервера.это код

Ниже приводится выдержка из кода и 

public class FetchByChangeIdLambda implements RequestHandler<RequestBody, String> {

    private static final String searchEndPoint=System.getenv("SEARCH_ENDPOINT");;
    @Override
    public String handleRequest(RequestBody changeId, Context context) {

        System.out.println("Did it even entered"+" "+changeId.getChangeId());       
        if(context.getLogger()!=null) {
        LambdaLogger lambdaLogger = context.getLogger();
        lambdaLogger.log("Search End Point is" + " " + searchEndPoint);
        lambdaLogger.log(String.format("Starting Search for Change Id,%s", changeId.getChangeId()));
        return GetResponseByChangeId.getResponse(searchEndPoint, changeId.getChangeId(), lambdaLogger);


        }

            return GetResponseByChangeId.getResponse(searchEndPoint, changeId.getChangeId(), null);

    }

POJO: 

public class RequestBody {


    private String changeId;

    public RequestBody(String changeId) {
        this.changeId=changeId;
    }

    public RequestBody() {

    }
    public String getChangeId() {
        return changeId;
    }

    public void setChangeId(String changeId) {
        this.changeId = changeId;
    }
}

AWS Local SAM Debug:

sam local —eventevent.json api -m GET -b «» | sam local invoke -d 5858 MicroserviceGetGateway

содержимое event.json 

{ 
  "changeId":1212
}
