Writing validator in JMWE to validate label containing at least one entry starting with a string


I've tried to search for a post but can't find one that matches. I would like to have a JMWE validator that makes sure that on the issue that I'm trying to transition, there is at least one (there may be several) labels that start with a certain string. No labels at all are not accepted.

Let's pretend that I have the requirement to have at least one label starting with "US-" - so "US-FL", or "US-TE" e.g.

So no label would give an error, one label saying "CA-OT" would not be OK but having two labels saying "CA-OT" and another "US-WY" would be OK as would having "US-AL" and "US-NY".

Hi @Ola Nissen ,

this is the Jira Expression you need for your Build-your-own Validator:

!!issue.labels && issue.labels.some(label => label.indexOf("US-") == 0)



Thanks for the quick answer. Tested and verified. Excellent help.
