Hi, I try to write my own scripted validator in JMWE.
when user create ticket and choose active sprint I want to show error message.
I dont know how use jira expression
did you read the documentation for writing Conditions and Validators in JMWE for Jira Cloud?
There is no "openSprints()" function in Jira expressions. However, to test whether the issue is in an open sprint, you can do:
issue.sprint != null && (issue.sprint.state == "active" || issue.sprint.state == "future")
