Cannot read property 'toString' of null

[GozPaez]

When I tested with the string recommended, receive the following message:

{
"errorMessage": "Cannot find module '/var/task/index'",
"errorType": "Error",
"stackTrace": [
"Module.require (module.js:596:17)",
"require (internal/module.js:11:18)"
]
}

Can you please help me in resolving the same,

@aviban @GozPaez What is the runtime are you trying to run this function? If you are using a runtime >=nodejs6.10 please try again since we released a major update and make sure you pull the latest version this repository.
