How to change the Help Page URL

Question:

Help page URL is not redirecting to a working URL.

When we try to access this page from SDC UI -> Help -> Help Contents, the page we are being redirected to is incorrect, therefore we see 404 error page.

Answer:

We can change the help page SDC points to following these steps:
1- On sdc.properties file change: 

ui.local.help.base.url=/docs
ui.hosted.help.base.url=https://www.streamsets.com/documentation/datacollector/3.8.1/userguide/help

by

ui.local.help.base.url=https://streamsets.com/documentation/datacollector/3.8.1/help
ui.hosted.help.base.url=https://www.streamsets.com/documentation/datacollector/3.8.1/userguide/help

2- Restart Data Collector.
