Is there a way to display record picker as a dropdown?

Hello, I am getting the list of employees who haven't been assigned yet to a request in the exp rule, but the interface is throwing error,

What corrections do I need to make?

While extracting the data from the "local!dropdowndata" using the index(), you need the pass the recordField with it's record's name like: recordType!RREmployeeRT.fields.name.
