Unable to output groovy result into Rest request step - ReadyAPI

Hi there,

Hoping someone can help. I have a Groovy script step that dynamically removes blank JSON nodes from a data source that appears to generate the intended result when run in isolation. I want to output this result into a REST request step. I have tried to use the "Get Data" function to output the property "result" from the groovy step. This runs without failures however, it appears to just generate blank requests.

I feel like I'm missing something quite simple. Please see attachment for context.

TIA!
