By any chance did you try reject( fn!isnull, Result) ??

By any chance did you try reject( fn!isnull, Result) ??

Try with this (from localtmp to the end , replace the name of your list)

a!localVariables(
local!inputArray: {1,2,3,4,5,6,7,8,9,10,"","","",""},
local!totalArray: length(local!inputArray),
local!maximumPerArray: 5,

local!amountArrays: ceiling(local!totalArray / local!maximumPerArray),
local!iterationArray: enumerate(local!amountArrays),
local!res:
a!forEach(
items: local!iterationArray,
expression: with(
local!leftAmountToCut: fv!item * local!maximumPerArray,
local!rightAmountToCut: local!totalArray - ((fv!item + 1) * local!maximumPerArray),

rdrop(
ldrop(
local!inputArray,
local!leftAmountToCut
),
if(local!rightAmountToCut < 0, 0, local!rightAmountToCut)
)
)
),

local!tmp:
a!forEach(
items: local!res,
/*expression: if(count(reject(fn!isnull,union(fv!item, fv!item)))>0, union(fv!item, fv!item),null)*/
expression: count(reject(fn!isnull,union(fv!item, fv!item)))>0
),

index(local!res, wherecontains(true, local!tmp))
