Hi, I was trying to update a file by changing old 204 terminal links to new 204.while connecting a link to Loop0200 it was throwing following error. The key input of component core.group-by cannot be computed, The key input must be a function of the node input or any of its descendants and constants. PFA.
Someone pls give me a solution for this.

Basically, the error means that if you have Loop2000 connected to the group-by function' nodes/rows input, then the connection to the key must ultimately (through functions or whatever) come from items which are descendants of that node (or, from constants). It cannot be connected in any way with an item which is not a descendant of that node. The solution for this is simply to correct the mapping.
