TraditionalBridge method returning string returns HTTP 500

[nkim-radley]

We have a method that returns a string (i.e., not an integer):

function methodname, a512

But calls to this function return the following:

ReportError: SYNERGEX.SYNERGYDE.SYNARGUMENTEXCEPTION: Argument specified with wrong size
