Cannot index "data" because it is an array type (List of Variant). Only fields with scalar types can be indexed from an array.

Hi, Im facing this issue when i'm retrieving  a list of data from an integration and  casting it to a data subset  when i try to acces a  especific id in a expression rule everything works perfectly 

and it returns an  id but  when i do the same thing on a process model  it throws me this error that you see i tried many ways of getting this to work  and nothing. what could it be the problem that  i'm facing ?

below how looks like  the expression rule when i  use the   process model to get the  values

this doesn't work either
