Hi @GA2021 ,
Could you please tell me:
Do you want to get a record returned by When an item is created instead of all records of the entire list?
Because When an item is created returns a record instead of an array, it is not possible to use Select directly.
You can use Get Items to filter out this record by ID (that comes with SharePoint) in the filter query.
I have made a test for your reference:
1. This is my data source.

2. Add Get Items and enter in filter query:

3. Use Select:

Best Regards,
Levi
