quarkus - 错误 [io.qua.ama.lam.run.AbstractLambdaPollLoop]（Lambda 线程（开发））无法运行 lambda（开发）：java.lang.NullPointerException

Question

我有一个用 quarkus 编写的 API，需要在 AWS lambda 上部署。在本地（调用的 API）中测试代码时，我遇到以下错误：

2022-01-12 13:49:52,210 INFO  [io.qua.ama.lam.run.AbstractLambdaPollLoop] (Lambda Thread (DEVELOPMENT)) Listening on: http://localhost:8080/_lambda_/2018-06-01/runtime/invocation/next
2022-01-12 13:50:45,215 ERROR [io.qua.ama.lam.run.AbstractLambdaPollLoop] (Lambda Thread (DEVELOPMENT)) Failed to run lambda (DEVELOPMENT): java.lang.NullPointerException

    at io.quarkus.amazon.lambda.runtime.AbstractLambdaPollLoop$1.run(AbstractLambdaPollLoop.java:110)
    at java.base/java.lang.Thread.run(Thread.java:834)

一定程度上引用了以下网址： https ://quarkus.io/guides/amazon-lambda

SiddhiLambda.java：

package com.scania.siddhiapi.lambda;


import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestStreamHandler;

public class SiddhiLambda implements RequestStreamHandler {  
    
    private RequestStreamHandler handler;

    @Override
    public void handleRequest(InputStream input, OutputStream output, Context context) throws IOException {
            handler.handleRequest(input, output, context);
    }   
}

有人可以让我知道我哪里出错了，是否可以在本地测试此代码而无需在 lambda 中部署。
