How can I use slack api in aws lambda?

Question

I want to use IncomingWebhook api of @slack/client in aws lambda function. There is something problems in my code. Please notice me how can I use.

This is my code below

const { IncomingWebhook } = require('@slack/client');
const config = require('./config')

exports.handler = (event, context, callback) => {
  const webhook = new IncomingWebhook(config.slack.webHookUrl)
  webhook.send('Hello there', function(err, res) {
    if (err) {
        console.log('Error:', err);
        context.fail('fail')
    } else {
        console.log('Message sent: ', res);
        context.succeed('succeed')
    }
  });
}

And This is my errors

{
  "errorMessage": "RequestId: 9e1b4362-259d-11e8-b422-91108e46ebe1
                    Process exited before completing request"
}

Here is console errors

This was due to a bug in the Slack client which was reported here: https://github.com/slackapi/node-slack-sdk/issues/479, and subsequently fixed in https://github.com/slackapi/node-slack-sdk/releases/tag/v4.0.1. A simple upgrade to the latest version (v4.3.1 at the time of writing) will fix this.
