Issue in the video below.
The result you’re getting is not a array and it’s a single result for the place_id you sent through the API call. When you add result as the results key nothing happens since it’s just a one record but when you add photos as a result key then you get successful call since there’s a photos array for that place and not just a single photo.
So you have to use a custom action to get the place details expect photos (but with custom action it returns the first image in the array). Then a external collection to get the photos of that place passing the place_id.
Let me know!
