Arcade dateDiff no work in expression date ( DASBOARD )

[MarceloCatalão]

very good evening, I'm trying to put the following code:

var endDate = Date('12/31/2023','MM/DD/YYYY')
var startDate = Today()
var age = DateDiff(endDate, startDate,'days')

I want it to return the number of days in an indicator

but when testing the value it presents me is null

is there any way to get around this problem?

thank you very much

It doesn't understand which value you're wanting to return. If you add this, does it return the expected value?

return age;
