How to represent [] on a condition

Hi guys,

 I have a intersection() function that return no values (image bellow)


Click to download = A new page with only []


My question is how can I represent that "[]" on a condition.



i´ve allready tried, is equal to null, is equal to "[]" but I get stuck with an error.


Thanks in advance.

Hello @JoaoSantos489 ,

the [] represents an empty array. To check if the output array contains any values you can use the empty(...) or length(...) expressions.

empty(Outputs) is equal to true


length(Outputs) is equal to 0
