heroku error Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

Question

I made a scraper with puppeteer and I didn't specified any port for serving it. it just runs and scrape data and exits with process.exit() command.

I deployed it to heroku with cli but after running it throw error:

Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch.
Stopping process with SIGKILL
Process exited with status 137

whats wrong?

Have you applied everything mentioned here: github.com/puppeteer/puppeteer/blob/main/docs/…? (heroku build pack installed, launch flags added) – Greig

yes i added buidpack – Plumbago

It's not clear when your scraper should run. You'll probably want to use a scheduler or clock. Examples of both are in Puppeteer on Heroku Error R10 (Boot timeout) Node (webscraping app) – Scrannel

Answer 1

Looks like you have a Web Dyno so the app must bind to $PORT.

You can instead define a worker (in the Procfile) if you do not need incoming HTTP requests.

Intervention

I'm not familiar with worker and Procfile, can you send me an example? – Plumbago
