Hey @gavraq,
Each set node creates one item with a single key, so you end up with three items, each having just one key:
I think what you want to achieve is one item with all three keys. Check if this solution works for your case:
You could actually put this in one set node (but this depends on the case—might be coming from different sources). Remember to set Input Fields to Include if needed
If you face more issues, I’ll be happy to help :3
