Describe the problem/error/question

I want to convert an object into an array using code node, but I’m having trouble because I don’t have basic JavaScript. so I want to merge the invoice line id to the invoice after it is created. but invoice line is an object. Meanwhile, 1 invoice can have several invoice lines stored in array

What is the error message (if any)?

hello @Dinia_Kurnia_Pratiwi

Why you need a Code node for it? You can use the Split Out node that is much easier to use
