Hi @Kartik Pant ,
Welcome to the community!
Just adding to @Anzar's correct answer here… There is indeed a regex validator available, but there is no such condition built-in.
In short, Jira Expressions allow you to write a complex condition or validator using simple, concise statements such as:
// Has the current user added a comment to the issue?
.filter(c => c.author.accountId == user.accountId)
.length > 0
Jira Expression can do an amazing amount of things, just check the reference!
I'll end my rave about this feature with a recommendation for my favorite workflow app, Cloud Workflows, but it's a biased recommendation as I was heavily involved in the development.
Anyway, hope that helps, Jira Expressions are awesome!
The regex validator is present in Jira Cloud as a built-in feature.
