Hi, I deployed my maven function and then invoked as below. But when I try to run docker image I get ClassNot Found error.

```
C02TX00EHV2H:hellome xx$ serverless invoke local  -f hellome --log

Below is my Handler class : (I used Maven, Java 11 runtime)
```
package com.serverless;

public class Handler implements RequestHandler<Map<String, Object>, ApiGatewayResponse> {
  private static final Logger LOG = LogManager.getLogger(Handler.class);

  public Handler() {
  }

  public ApiGatewayResponse handleRequest(Map<String, Object> input, Context context) {
    LOG.info("received: {}", input);
    Response responseBody = new Response("Go Serverless v1.x! Your function executed successfully!", input);
    return ApiGatewayResponse.builder().setStatusCode(200).setObjectBody(responseBody).setHeaders(Collections.singletonMap("X-Powered-By", "AWS Lambda & serverless")).build();
  }
}
