@talaikis You probably already figured this out long ago, but just in case for anyone who may be reading...

This is because chart.js (required peer dependency) isn't installed. It's really easy to miss in the Getting Started instructions, but it's there. Got me too. 😅

npm install chart.js

yarn add chart.js

@MastaAaron This has been added as a dependency and still getting the error:

{
    "errorType": "Error",
    "errorMessage": "Cannot find module 'chart.js'",
    "code": "MODULE_NOT_FOUND",
    "stack": [
        "Error: Cannot find module 'chart.js'",
        "    at Function.t [as resolve] (/var/task/src/handler.js:1:1002)",

        "    at Runtime.handleOnce (/var/runtime/Runtime.js:66:25)"

}

package.json looks like this:

Any other ideas?
