Why is it showing a 500 error on the server?

Question

Java

There is a simple site checker https://github.com/CptWasp/PGBonusParser
Cromedriver visits the site https://qrfinex.com/stocks , clicks on the BGBONUS tab, gets the text from the element, and sends a personal message to VKontakte.

Everything works great on localhost, after which I uploaded it to heroku.com,
it returned a 500 error

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
Timed out waiting for driver server to start. Build info: version: 'unknown', revision: 'unknown', time: 'unknown' System info: host: 'cfdb7b7d-f689-44d6-aeb5-2be9e9d6f3b2', ip: '172.16.92.142', os

Answer 1

Timed out waiting for driver server to start.
Your driver did not start and a timeout occurred. Check your chromedriver paths first
