Github bot - Unexpected token ; - Glitch

Question

I'm trying to build my own github bot to cherry-pick pull-requests into release branches. There are several examples in Javascript/Typescript and using/not using Probot (Github) available on github:

• Cherry-pick bot (Typescript + Probot)
• Here's some sort of guide

At the moment I can successfully run my bot locally, but it's not working when deployed to Glitch.

Here's what I did

npx create-probot-app issue_greeter
? App name: issue-greeter
? Description of app: Replies with a greeting when someone opens an issue
? Which template would you like to use? basic-ts => Comment on new issues - written in TypeScript
code issue_greeter

I want this bot to reside under my organization. So while normally you would do the following:

npm start
# Visit http://localhost:3000
> Register Github app
# Visit https://github.com/settings/apps/manifest

I'm doing this manually:

• Visit smee.io

• Click Start a new channel

  • Webhook Proxy URL = https://smee.io/2TJ4whCGVUpsHdRr
  • Webhook Secret = bJpKnpXCsnhoJYU6O9Z5CEy6eSZ45tdP (random string 1)

• Now move to the project. Copy .env.example as .env and paste the WEBHOOK_PROXY_URL and WEBHOOK_SECRET

• Visit the Apps page under your Github Organization (https://github.com/organizations/ORGNAME/settings/apps) and click New GitHub App

Here are all other instructions I did (and wrote down while doing them)

But for some reason my Glitch app won't start, and gives the following error:

There's no WEBHOOK_PROXY_URL, but a WEBHOOK_URL here (as per instructions).

Note that the generated bundle is already CommonJS

• Github repository
• Node version: 10.24.1 (which is like out-of-support for over 3 years by now)

What's causing this. I noted somewhere that Glitch seems to be using Node 10, but since everything is locally built that shouldn't be a problem?

Also, is the SMEE-channel still used when deployed to Glitch, or is this only for development?
