Google Sheets Node Only Returns First Row with Dynamic JavaScript Input

I'm using a Google Sheets node to read rows and then pass the data into an HTTP Request. While the node preview shows all rows, when I switch to using the dynamic JavaScript input schema only the first row is processed, even though all rows have been read successfully.

I haven't received any error messages, so it appears the failure is in how the dynamic input is handling the data. Below are the workflow snippets for both the Google Sheets node and the HTTP Request node that I'm working with:

The node output preview images are included in the original post. Any insights into why only the first row is being processed with the dynamic JavaScript input would be greatly appreciated.
