Simple code won't work on 3.2.0 & 4.0.0
Hello, I am running on an AWS Lambda using winston papertrail and for some reason, the lambda won't respond on 4.0.0.
You'll find the code here (to test, replace with own papertrail host/port) https://gist.github.com/quentinfasquel/78630bb57a7ab9a440f2a88f9acd5272
The app works super fine under express locally and I believe the issue is specific to AWS Lambda along a usage of winston-papertrail logger and alexa-app 4.0.0. If the winston logger is closed (papertrail connection is closed) and the alexa-app 4.0.0 will respond, but the logs aren't sent. Without closing, the logs are sent but it will take too long and say "the requested skill...", but alexa-app 3.2.0 works fine with that.
And the logs..

@quentinfasquel it's difficult to tell, but I think the issue may be due to the fact that the lambda callback is waiting for an empty event loop but if you keep the papertrail connection open, this will not occur. I'm not sure why manually closing it prevents the logs from being sent, though.
Prior to 4.0.0, we were using .context to end the lambda function rather than .callback. You can set callbackWaitsForEmptyEventLoop = false:
exports.handler = (event, ctx, callback) => {
ctx.waitsForEmptyEventLoop = false;
alexa.request(event)
.then(response => callback(null, response))
.catch(callback));
}
