Promise support (Node.js8)

[valonhaliti]

When passing data with callback it's working fine (the Next state is being triggered).

export const handler = (event, context, cb) => {
    cb(null, {
       data: result
     });
};

But when I'm using async functions (promises) instead:

export const handler = async event => {
    return {
       data: result
     };
};

It's not working, the process is shutting down. The Next state it's not being triggered at all.

Hey guys. I'm also getting this bug. This project probably isn't maintained anymore.
