Can't get jsonToArray in standalones ?

[Ben Rubinstein]

Building a standalone that uses jsonToArray.

Works fine in the IDE.

If I use "search for required inclusions" when building the standaline, then 
when the script calls jsonToArray it throws error 219 (Function: error in 
function handler).

If I use "select inclusions", and check "JSON Library", then it crashes.

Interestingly, if I *uncheck* "JSON Library" from the inclusions, then it also 
crashes! (I expected it would throw error 219.)

This is the same on LC 9.6.6 and 9.6.7; and (at least the crash) same on both 
Mac and Windows.

My best guess is that I need to have something else checked in the inclusions 
- any suggestions?

TIA,

Ben
