Pure VXML application works in ExperiencePortal 8.1.1 and earlier but fails in version 8.1.2

VXML calls a REST service using <data> and the service worked based on logging.

<data maxage="0" name="User" srcexpr="lookupUser(aCode, connection.call_tag)" fetchaudio="/alert_messaging/resources/speech/percolate.wav" method="get" accept="application/xml"/>
<var name="rootdoc" expr="User.documentElement"/>

However, when the vxml tries to access the resulting DOM object, it fails and gives the following error in the VB logs:

Hi.

That is an ECMA error, your script attempted to access an object property (User.documentElement) which was not found/doesn't exist/ is undefined.

Yes, this is an ECMAScript error. The ecmascript interpreter in EP8.1.2 has been upgraded to MozJS52.
I've been reading that the DOM support has been removed in this script interpreter.

But is there any other way to access the variable returned by the <data> call in this EP version since <data is supported in VXML2.1? This code worked in EP earlier versions.

Any help is appreciated.

Hi.
Developers opened the Jira EPCFD-539 and are currently working on that. No other info provided (deadline, etc...).

The Jira EXPPORTAL-14115 was opened to fix this issue with <data> tag.

The fix was released with the patch MPP 8.1.2.0.374, download here
