Automation to edit Asset field with values from object attribute that holds multiple objects

[Michael Frade]

Trying to build an automation that is editing a work item field with the value from an Asset object attribute. This attribute is a reference to another object and can hold multiple objects. If it the object holds multiple object references, I want all objects passed into the Asset field.  Right now it is only passing the first value.  The asset field is set to allow multiple objects. I can manually add both Keys without issue.

When I log the smart value it returns as [Key-1, Key-2]. Key-1 is showing in the Asset field but not Key-2.

The AQL in the edit work item actions is - Key in {{Smart Value}}

Any recommendations on how to format the smart value or the AQL query to get the asset field to populate with all the objects in the referenced attribute?
