Lambda runs on either Node v4.3 or v6.10. Both versions don't support ES6 modules.

You have to configure your transpiler to transpile to ES5.

For local development, I would suggest you use the same Node version that you use in Lambda so you don't have these "but it works on my local!" moments.

Something else it could be. I was getting this issue a few versions of Serverless back when deploying functions individually.

The rub was if you deployed the function individually web pack didn't refactor the es6 down.

So if you find you deploy and its ok then you deploy a function by itself and it gets this error then update serverless and all your plugins and this will go away. (from memory I got past this at about v1.19.0

it was actually runtime being set to nodejs6.10 instead of nodejs8.10, but that put me on the path to solution. thanks
