I have a requirement wherein I need to make a field mandatory based on values selected in the first drop down of a cascading custom field, while performing a transition. The user needs to update certain fields on a custom screen before the transition is executed.
I am trying to add a simple validator script for validating the value in first drop down of the Cascading list, but ran into this error. I don't have a background in groovy scripting or any programming whatsoever, but passionate to expand my knowledge on this.
I have been a JIRA admin for about 2 years now, but never required to create any scripts so far. Any kind of assistance will be really helpful !
Also, looking for suggestions on beginner-level learning materials for scripting in JIRA.
