Screenshot form Script Editor.

Starting with Release 14, the following statement in JavaScript for Automation (haven't tested in plain Applescript yet) returns &quot;Error -1700: Can't convert types.&quot;

var stp = Application(&quot;Safari Technology Preview&quot;); 
(stp.windows[0].currentTab().url()); 

Switching to either Safari or WebKit nightly works. The issue has persisted with Release 15.</pre>
