🚀 go-pugleaf

I've been looking at this JS to see how it works and in ExtendScript Toolkit I get the following error:

Invalid value for parameter 'showingOptions' of event 'place'. Expected Boolean, but received (0, 0)

Line 186

myPDF = myFrame.place(File(myFile),[0,0],myPDFLayer,false,true,true,true);

This script is from the Adobe Exchange:

If you change (0,0) to false you get:
Invalid value for parameter 'showingOptions' of event 'place'. Expected Boolean, but received (FALSE)

Isn't a Boolean = true or false?
