I need to send an email to a group (I believe a Jira group) if one of 4 user picker fields is empty.
The only plugin I seem to have available at my disposal to do this is ScriptRunner, and it requires syntax which I am woefully unfamiliar with.
Before sending me hatemail about an answer being out there, please know that I tried looking and I saw various examples showing various ways of dealing with a single user picker field, but not how to create a condition in which any of multiple fields is empty. (null)
