Generate issue links in Jira with scriptrunner

I am trying to generate some issue links in jira, here is my code. This code is executed as a Jira automation rule after clicking on a button. The problem is that I receive the following error message. They say that the issuelinktype is wrong, anyone knows how to figure out which issue link type I need?
