Is your StreamHandler class called exactly HelloWorldSpeechletRequestStreamHandler that you specified under Handler in Function code section in Lambda? If so, is the path the same in your project as helloworld.HelloWorldSpeechletRequestStreamHandler?

@bearbearcow hi, can you provide more details? What SDK are you using? How did you configure your lambda function and skill? Or you can provide your Stream Handler code here so that we can help you.

Looks like you are referring to the old version SDK. We have V2 SDK Hello World sample here. For this example, in lambda function - Handler, it's helloworld.HelloWorldStreamHandler.

Hope it helps. Feel free to re-open this issue if you have any questions.

Hi, thanks so much for your advises! I got problem when testing helloworld sample in ask sdk. I'm using alexa-skills-kit-sdk-for-java/samples/helloworld for testing, it's the latest version i download from github. I havn't change any code in helloworld sample. and build the jar package wihth command : "mvn org.apache.maven.plugins:maven-assembly-plugin:2.6:assembly -DdescriptorId=jar-with-dependencies package" after that i upload target jar file "helloworld-1.0-jar-with-dependencies.jar" to lambda。

In Lambda function - Handler，i have tried to fill some handlers, but they didn't pass。 Here is the handler i filled in Lambda function handler and the test results: 1.com.amazon.ask.helloworld.HelloWorldStreamHandler test result: { "errorMessage": "2018-09-13T01:36:23.210Z 6922c86e-b6f5-11e8-854d-01b6da6a9a5d Task timed out after 3.00 seconds" }

2.com.amazon.ask.helloworld.HelloWorldStreamHandler::HelloWorldStreamHandler test result: { "errorMessage": "No public method named HelloWorldStreamHandler with appropriate method signature found on class class com.amazon.ask.helloworld.HelloWorldStreamHandler" }

3.helloworld.HelloWorldStreamHandler test result: { "errorMessage": "Class not found: helloworld.HelloWorldStreamHandler", "errorType": "java.lang.ClassNotFoundException" }

4.helloworld.HelloWorldStreamHandler::HelloWorldStreamHandler test result: { "errorMessage": "Class not found: helloworld.HelloWorldStreamHandler", "errorType": "java.lang.ClassNotFoundException" }

the attachement is my helloworld jar package. How can i fix this problem？Look forward to your replay.

@bearbearcow hi I can't see your attachment on github, but you are on the right track, in Lambda function - Handler: com.amazon.ask.helloworld.HelloWorldStreamHandler.

I just ran a end to end Hello World skill test and also test on lambda, everything looks good.

1. I suspect you used a wrong format json input when test on lambda. You can use Alexa Start Session Event Template. It should execute successfully.

2. You can also test on developer console , which provides you a better user-friendly testing UI.

Hope it helps.
