lambda function entry point is not accesible

[ttruga]

Im using the single-stream folder with the sdkv2 branch, followed all the instructions in order to configure all permissions. Tried testing the skill from both the developer console and also executing

ask simulate -l en-US -t 'play my radio'

I always get on cloud watch the following error:

Unable to import module 'dist/index': Error
at Function.Module._resolveFilename (module.js:547:15)
at Function.Module._load (module.js:474:25)
at Module.require (module.js:596:17)
at require (internal/module.js:11:18) 

I also changed the handler as mentioned on the README file using the following command:

aws lambda update-function-configuration --function-name ask-custom-myradio-default --handler dist/index.handler --runtime nodejs8.10

I also tried executing the lambda function directly from the lambda dashboard using the pre populated example events and I always get the same response.. it can't find the entry point to the lambda function.

Sadly because the function is too big so is impossible to edit it inline in order to detect which is the actual entry point of the function.

it is always:

{
  "errorMessage": "Cannot find module '/var/task/dist/index'",
  "errorType": "Error",
  "stackTrace": []
}

Anybody knows why is this happening or perhaps which one is the actual entry point for the function? or perhaps there is a way of not using TS so it can behave like a typical ES6 JS function?

I'm also getting the exact same CloudWatch error:

@ttruga did you find a solution?

@sebsto I don't suppose you could help us out here could you please?

By exporting my Lambda function (Actions > Export function) I can see that there is no dist directory in there:

So is the question, in my case at least, what failed to build the dist JavaScript?

[benappware]

OK, so the reason is that because this is a TypeScript project it first needs compiling into JavaScript.

So the missing command just before "ask deploy" is: (cd lambda && tsc)

Then you get a single-stream/lambda/dist/ directory (due to the settings in single-stream/lambda/ts-config.json):

$ ls -al lambda/dist/

And that needs running every time you change a .ts file, unless you have a watcher or such like running I guess.

Looks like you nailed it down. I forgot to add Typescript compilation instructions. I will update the readme over the weekend. Thanks for helping !
