Passing keyed structures between JavaScript nodes

I'm having a heck of a time trying to figure out how to work with keyed structures that are passed between JavaScript patches.

For instance, in the first JavaScript patch, I have this...

function (__structure outputStructure) main ()
{
   var result = new Object();
   result.outputStructure = new Object();
 
 var myStructure = new Object();
    myStructure.something = new Object();
    myStructure.something.amazing = new Object();
    myStructure.something.amazing.here = "yes";
 
    result.outputStructure = myStructure;
 
 
   return result;
}

outputStructure is then connected to myStructure of JavaScript patch number two...

function (__string somethingamazing) main (__structure theStructure)
{
   var result = new Object();
 
       result.somethingamazing = theStructure.something.amazing.here;
 
   return result;
}

I expect somethingamazing to return "yes", but instead I am left with a persistent error:

TypeError:  Result of expression 'theStructure' [null] is not an object.

I originally encountered this problem when I was attempting to make use of the structure output from the MIDITools plugin, so I suppose the problem doesn't have to do specifically with passing keyed structures between JavaScript patches, but that I'm simply doing something wrong with trying to get the structure into JavaScript.

I feel, as I so often do, that I am missing something extremely obvious. Can anyone shed some light on my mistake?
