I figured out that I should’ve included Array Aggregator to get all URLs after ‘Fill a PDF’ module, and set ‘Search Records’ as Source Module for Array Aggregator.
I also needed a formula {{join(map(33.array; "url"); ",")}} in the ‘Merge a PDF’ module to get all links from the Aggregator. When I set just Array|URL as the source, I received only the first URL from the bundle.
