Is there a node to replace a sublist at a specific position? I want to replace the last sublist of a list with another list. The first time (with the orange and blue group) it has worked with List.ReplaceAtIndex, but I think the second time with the green List, it doesn’t work because the list is not regular. What can I do to replace a very specific sublist (the last) with another list?

> I have a problem with Replace By Condition Node. When I have a list wich just one item and sublists, the node doesn’t work. The warning is “\_Converting an array to var would cause array rank reduction and is not permitted”. but if I have a list only with sublists (even if sublists have only one item), it works. Do you have and idea : either to convert list to have all item in sublists. I tried with List.slice but It doesn’t work very well. or a node like Replace By condition to wo…
