Hi,
Im new to everything Jira and I have tried to figure this out.
I have been trying to create an email rule that is suppose to run when an issue is created. The rule only contains one thing which tells the assignee which priority the ticket has (since the standard "a ticket has been assigned to you" cant be edited).
So the rule looks like this:

And I get an error saying "The To field is empty". No matter what Conditions I pick, I get the same error message. The "priority?" is our own field we created for this specific project.
We have other rules in this project that auto assigns a ticket depending on X factors.
What am I doing wrong?
