I'm a beginner with javascript/web development. But I'm trying to do a Slack bot which uses Github API. I would like to post a message on Slack when a Github release is created. I use Octokit library to request my URL.

const octokit = new Octokit({ auth: process.env.GITHUB_AUTH });

const getReleaseTrigger = async function () {
  const res = await octokit.request('POST /payload', {
  });
  const resJSON = JSON.parse(res);
  return resJSON
};

(async () => {
  await app.start(process.env.PORT || 3000);
  try {
    const releaseTrigger = await getReleaseTrigger();
    const slackBodyGithubMessage = {
      mkdwn: true,
      text: `*${releaseInfo}*`
    }

    const res = await request({
      url: `https://hooks.slack.com/services/${hookPersonalMessages}`,
      method: 'POST',
      body: slackBodyGithubMessage,
      json: true
    })

  } catch (e) {
    console.log('our error', e);
  } debugger;
  console.log('Slack app is running!');
})();

It's strange cause, my console respond this when I launch my app :

our error RequestError [HttpError]: Not Found

    status: 404,
    headers: {

      'access-control-expose-headers': 'ETag, Link, Location, Retry-After, X-GitHub-OTP, X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Used, X-RateLimit-Resource, X-RateLimit-Reset, X-OAuth-Scopes, X-Accepted-OAuth-Scopes, X-Poll-Interval, X-GitHub-Media-Type, Deprecation, Sunset',
      connection: 'close',
    [....]

BUT my console Ngrok detect when I create a new release on my repo : screenshot Ngrok

It send me a "good" response (despite the 404 error displayed), with a good ref/title (in this case : test21, this is the title I put on the release on github) with ngrok console. Futhermore, my local console write 5 times this sentence : " [INFO] Unhandled HTTP request (POST) made to /payload "

It seems to detect my repo, and react well when I create a new release. But I can't access the answer in my Slack message. And the 404 error seems strange to me. And I don't understand why it notice me 5 times for each release created.

I would like to get the title and the description of the release just created. Do you have any idea how to do this?

Thanks a lot for your future response

Have a good day
