Exception while clicking button on UWL that launches WebDynpro Application

Question

Hi All,
I am getting a portal runtime error while clicking on Button thatu2019s there in UWL. When user clicks on this button a webdynpro abap application should get launched. However we are getting exception. Button is added via UWL configuration file. Everything is working fine in Development system however this issue is there in QA system only.
Here is the piece of code written in UWL configuration file.
