C0000005 ACCESS_VIOLATION Exception with Progress Openedge when calling a Web Service

I am trying to hit an external web service using Progress OE 11.5. When I execute the code from GUI Procedure Editor or the CHUI Procedure Editor, it crashes when calling the API

RUN ProcessTrack IN hTrackPortType(INPUT lcRequest, OUTPUT lcResponse) no-error.


I don't get any errors. The progress GUI window just crashes.

When I traced the logs it has "C0000005 ACCESS_VIOLATION" exception. Any idea why this is caused? But when I access the same web services from SoapUI or from a Python program it works fine. I am not sure if Progress OpenEdge has any access restrictions to contact the apis.

I have the full stack trace here.
