I am new to DWR

I am facing an issue in the application while loading a DWR Ajax call from JavaScript. However, the DWR ajax call is working properly in our local Tomcat and Weblogic server, but in our client onsite Tomcat environment we are getting the below mentioned exception. We are using dwr-3.0.2-RELEASE.jar

Please suggest what might cause this issue as this is working properly in our local Tomcat server and only getting this Exception at client Tomcat Server. Please note the Tomcat version is 8.5.72 and Environment is linux(RHEL)
