Bot using Nightmare returns undefined on Heroku, what's wrong?

Question

JavaScript

I deployed a bot that parses a cargo transportation site, when I launch it at home, everything works as it should. When uploaded to Heroku it returns undefined. Is it even possible to properly deploy this bot on Heroka?

Answer 1

for nightmare you need a screen, on a Linux vds, for example, you need to install x11 tools.
so it’s unlikely that it will start so easily, however, at the request of heroku nighmare, Google finds some ready-made options for building on heroku
, and by the way, instead of nightmare, I advise you to take a closer look at puppeteer, because the first one has not been supported for a long time
