title: Null Pointer Exception in AWS lambda without any stacktrace
body: <p>I have created an AWS Lambda. In cloud watch I can see the Null pointer exception without any stacktrace. All I can see is the below exception and I'm not really sure where it's happening.</p>
  
  <p>For sure the exception is throwing before coming to the <code>handleRequest</code> method. Just after constructor processing. But the lambda is working fine as expected.</p>
  
  <p>Exception:</p>
  
  <pre><code>java.lang.NullPointerException

  at java.lang.reflect.Method.invoke(Method.java:616)
  </code></pre>
  
  <p>Code:</p>
  
  <pre><code>public class Hello implements RequestHandler&lt;Object, String&gt; {
  
      public void Hello(SNSevent snsEvent){
        this.snsEvent = snsEvent;
      }
  
      @Override
      public String handleRequest(Object input, Context context) {
  
  
          // TODO: implement your handler
          return "Hello from Lambda";
      }
  
  }
  </code></pre>
  
  <p>Can anyone suggest what's happening here?</p>
