In the attached screenshot, I have removed the unnecessary nodes/modules to make it simpler to explain
Basically, at (2), I am receiving 4 records, but to continue, I also need the set value at 1 (which shows up only once for the 1st record), and the remaining 3 records are incomplete at merge.
How can I get the set value to persist? I saw a similar question where the answer was to merge by index. I am fairly new to n8n and don’t understand how does the merge by index work because I don’t see any such option in merge node.
