Trouble assigning ticket in automation from Service Desk Form

[Jonathan Domanus]

I'm having an issue...

I have a Jira Service Desk form with a field "Single User" in it. The field has a property under "LINKED JIRA FIELD" to "Assignee"

Then I have an Automation rule to create additional tickets in another project, and I want to assign the additional tickets to that user that was selected in the Single User. 

I'm getting an error "

Unknown fields set during create, they may be unavailable for the project/type. Check your custom field configuration. Fields ignored -

Assignee (assignee)"

Which is odd because this isn't a custom field, but a regular Jira field. Any ideas?

I found the problem and resolution. The issue was that I did not have the Assignee field as part of the create screen for the issue type in question. I added that in as well as set the field in Automation

• Choose field to set: Assignee
• Value: Copy from trigger issue

Now the subsequent tickets will be assigned to the proper user selected in the previous field.
