That’s what happens when Group By is used. You’ll need to use a Set Variable module to extract the first item in the array, if that’s what you want.
Alternatively, you can avoid using Group By, then, you can use this built-in function in a Set Variable module after the aggregator:
- distinct
distinct(array; [key])
Here’s an example of how you can use this function:
{{ distinct(86.data.items; id.videoId) }}
(copy-paste the above into the field, or type it exactly as shown)
Hope this helps! If you are still having trouble, please provide more details.
