I am trying to create a simple lambda function, and I'm running into an error.

My code is basically

console.log('Loading function');



exports.handler = function(event, context) {

    console.log('value1 =', event.key1);

    console.log('value2 =', event.key2);

    console.log('value3 =', event.key3);

    context.succeed(event.key1);  // Echo back the first key value

    // context.fail('Something went wrong');

}

in a helloworld.js file. I zip that up and upload it as a zip file in the creating a lambda function section, and I keep getting this error:

{

  "errorMessage": "Cannot find module 'index'",

  "errorType": "Error",

  "stackTrace": [

    "Function.Module._resolveFilename (module.js:338:15)",

    "Function.Module._load (module.js:280:25)",

    "Module.require (module.js:364:17)",

    "require (module.js:380:17)"

  ]

}

Does anyone have any ideas?
