Long running response / setTimeout not being called

What is the longest an Alexa skill can wait before responding… Here’s some sample code that I’ve been testing out (on both Lambda & on a express / Node version too).

const alexa = require('alexa-app')
const app = new alexa.app('my-long-running-app')

app.intent('SampleIntent', {
  'utterances': ['sample']
}, (req, res) => {
  return new Promise((resolve) => {
    setTimeout(() => {
      res.say('I waited a minute')
      resolve()
    }, 60000)
  })
})

The setTimeout is more just a placeholder for a long running function. The above code does work usually in the ~30 seconds range, but will go completely unresponsive around ~40+ seconds (And will only time out after a few minutes and say "there was a problem with the … ").

That’s what I was getting to. The problem is not your code, it’s the Alexa platform that’s timing it out, I suspect it’s a hard-coded limitation.

As I mentioned before, bring this up on an alexa dev forum or something like that. It will be helpful for the next person and PR an update to README here somewhere in asynchronous responses once you get a definite answer from Amazon.

Can we document (and link) this in README please? Care to PR?
