I want to add ticket reporter as by default assignee in case of unassigned tickets
Hi @prasant.dubey and welcome to the community,
You can't do that by using JQL. JQL yields issues.
What you want is either use Jira automation to create a rule for newly created issues, and to place the reporter as assignee (provided that the reporter has the corresponding permissions), OR
create a post function within your workflow to do the exact same thing.
You must be a registered user to add a comment. If you've already registered, sign in. Otherwise, register and sign in.
