在Java中使用AWS Lambda打印“ Hello World”时观察到JsonMappingException

Question

以下程序是要与AWS lambda一起执行的POC。我想在控制台上打印Hello World。

package com.example.main;
public class HelloWorld {

public static void main(String[] args) {
    // TODO Auto-generated method stub
    System.out.println("***********Hello World**********");
 }
}

我创建了一个可运行的jar并尝试使用AWS lambda执行，但是观察到以下异常：

    {
  "errorMessage": "An error occurred during JSON parsing",
  "errorType": "java.lang.RuntimeException",
  "stackTrace": [],

    "errorMessage": "com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of java.lang.String out of START_OBJECT token\n at [Source: lambdainternal.util.NativeMemoryAsInputStream@1e88b3c; line: 1, column: 1]",
