I’m trying to work through the n8n intro course and keep getting stuck on appending data retrieved from HackerNews to my AirTable. I had this same course working several weeks ago and restarted to pick it back up.

I’ve looked through these forums trying to find a similar issue somebody’s had, which I haven’t so that makes me think I’m doing something wrong somewhere.

I figured it out, as expected I had missed one step in the previous process to ‘split into items’ the returned http GET.
