Trying to use Katalium Server but getting error and can't find guides

Hi, I’m trying to run my Katalon tests through the Katalium server as given by this link https://docs.katalon.com/katalium-server/docs/katalium-user-guide.html#set-up-katalium-server, but it seems as though this webpage is the only resource available and my server is stuck on step 3 of the guide essentially (running standalone batch file for windows results in thousands of lines of errors). I think the main issue is this


but I don’t know how to fix it. Can anyone help? Thanks
