Hi @Phildefer
Thanks for clarifying! I understand what you’re trying to do now.
So essentially, this loop that you are trying to create in the HTTP request node, is the entire logic of the Split Out node.
You cannot achieve the same thing because our expressions will always evaluate into one single item (array). This output is what you need to loop over and that’s exactly what the Split Out node is doing.
I hope this makes sense? I think your workflow is very ok
