Hi all, I am using GReg 4.6.0 and running `Issue Tracker Sample <https://docs.wso2.com/display/Governance460/Issue+Tracker+Sample>`. After creating the RXT artifact it is working as expected.
At the last step, it is needed to subscribe for notifications. <https://docs.wso2.com/display/Governance460/Issue+Tracker+Sample#IssueTrackerSample-SubscribingToNotifications> I have added the followings to the $GREG_HOME/repository/conf/*registry.xml*. <workList serverURL="local://services/" remote="false"> <username>admin</username> <password>admin</password> </workList> Finally added subscription with the role `internal/everyone`. [image: Inline image 2] But notifications are not seen as expected when changes are done for the LC. Instead following error trace is shown; *[2015-02-23 16:31:33,218] ERROR {org.wso2.carbon.humantask.core.integration.AxisHumanTaskMessageReceiver} - Task creation failed.* *org.wso2.carbon.humantask.core.engine.runtime.api.HumanTaskRuntimeException: Error occurred while calling to realm service for operation isExistingRole* at org.wso2.carbon.humantask.core.integration.CarbonUserManagerBasedPeopleQueryEvaluator.getUserNameListForRole(CarbonUserManagerBasedPeopleQueryEvaluator.java:71) at org.wso2.carbon.humantask.core.engine.util.CommonTaskUtil.nominate(CommonTaskUtil.java:320) at org.wso2.carbon.humantask.core.dao.jpa.openjpa.HumanTaskDAOConnectionImpl.createTask(HumanTaskDAOConnectionImpl.java:56) at org.wso2.carbon.humantask.core.engine.HumanTaskEngine.createTask(HumanTaskEngine.java:81) at org.wso2.carbon.humantask.core.engine.HumanTaskEngine.access$000(HumanTaskEngine.java:38) at org.wso2.carbon.humantask.core.engine.HumanTaskEngine$1.call(HumanTaskEngine.java:97) at org.wso2.carbon.humantask.core.engine.HumanTaskEngine$1.call(HumanTaskEngine.java:93) at org.wso2.carbon.humantask.core.scheduler.SimpleScheduler.execTransaction(SimpleScheduler.java:880) at org.wso2.carbon.humantask.core.scheduler.SimpleScheduler.execTransaction(SimpleScheduler.java:829) at org.wso2.carbon.humantask.core.engine.HumanTaskEngine.invoke(HumanTaskEngine.java:93) at org.wso2.carbon.humantask.core.integration.AxisHumanTaskMessageReceiver.invokeBusinessLogic(AxisHumanTaskMessageReceiver.java:74) at org.apache.axis2.receivers.AbstractMessageReceiver.receive(AbstractMessageReceiver.java:110) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:180) at org.apache.axis2.transport.local.LocalTransportReceiver.processMessage(LocalTransportReceiver.java:169) at org.apache.axis2.transport.local.LocalTransportReceiver.processMessage(LocalTransportReceiver.java:82) at org.wso2.carbon.core.transports.local.CarbonLocalTransportSender.finalizeSendWithToAddress(CarbonLocalTransportSender.java:45) at org.apache.axis2.transport.local.LocalTransportSender.invoke(LocalTransportSender.java:77) at org.apache.axis2.engine.AxisEngine.send(AxisEngine.java:442) at org.apache.axis2.description.OutInAxisOperationClient.send(OutInAxisOperation.java:398) at org.apache.axis2.description.OutInAxisOperationClient.executeImpl(OutInAxisOperation.java:224) at org.apache.axis2.client.OperationClient.execute(OperationClient.java:149) at org.wso2.carbon.governance.notifications.worklist.stub.WorkListServiceStub.addTask(WorkListServiceStub.java:183) at org.wso2.carbon.registry.eventing.RegistryEventDispatcher.notify(RegistryEventDispatcher.java:381) at org.wso2.carbon.event.core.internal.notify.CarbonNotificationManager.sendNotification(CarbonNotificationManager.java:62) at org.wso2.carbon.event.core.internal.delivery.Worker.run(Worker.java:52) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) *Caused by: org.wso2.carbon.user.core.UserStoreException: Invalid operation.

Any thoughts on this error?
