Is there a bug in Venu2Plus getStressHistory?

if ((Toybox has :SensorHistory) && (Toybox.SensorHistory has :getStressHistory)) {

var itr = Toybox.SensorHistory.getStressHistory({:period=>1});

With this code I was able to get stress values last week!
However, when I run it today, I get an error that there is no symbol for getStressHistory and I cannot get it.

In Venu2Plus, the above error
VenuSQ Music and Fr255 work as expected
