Copy current assignee to another custom field using post function in Jira cloud

[Ouioui Zhou]

Hi there. I would like to set a post function so that when user create an issue, the value in current assignee can be copied to another custom field "Approver (Supervisor)". 

Approver (Supervisor) is a User Picker (single user) field.

I tried set up with post function but "Approver (Supervisor)" is not an option in the destination field list.

The destination fields only allows the following parameter. 

How can i copy the assignee to the custom field? Is there any solution to my request without add-on? 

Thanks a lot!

Hi @Ouioui Zhou can you start writing the field's name? There is an autocompletion implemented in the field.
