Although I'm following the steps explained on this page (https://legacysupport.timextender.com/hc/en-us/articles/360034695651-Connect-to-a-REST-API), I can't figure out what's going wrong.
Situation: I have a REST API, with two endpoints: one for fetching all locations (locationId) and one for fetching all reviews per location. I need the locationId from the first request, iterate trough all locationId's and request the reviews per location.
First request is working perfectly, REST.json is loaded with all locations.

For the second request, I've edited the RSD file, with an input parameter and filter (I know, the URL is mentioned twice, don't know which one is correct):

Then I added a dynamic filter:

However, no results. Does anyone know what I'm doing wrong? Can someone point me in the right direction? Thanks in advance!
