"elem.getClientRects is not a function" error when using Date Picker

ASP.NET MVC Core app

I get "elem.getClientRects is not a function" when clicking on the control to open the calendar.  If I enter the date using text the control works but the calendar pop up never opens when clicked.

It worked with earlier jquery versions but when I moved to 3.1 (for compatibility with another lib) it stopped working.  I am using the kendo bootstrap themed libraries and bootstrap 3.3.7.

Thanks
