How do I populate a drop down box from a simple query

I have the following code:

{{ => {
   return {
       label: qry_lpn.strPlate,
       value: qry_lpn.strPlate

I am getting the error

path:value must be unique. Duplicate values found

The query only returns distinct items. So there are no duplicates. I am at a loss at what to do next.

Hey, Welcome to the community.

This error comes up only where there are duplicate entries in values. Can you check if copy pasting the response object directly in the select options work? If it does, it might be something to do with the evaluation engine
