Description of problem:

I am trying to with below API's to list the HumanTask assigned to group through Remote REST API's but it fails with exception:

~~~
Unable to execute GetTaskAssignedAsPotentialOwnerCommand/0: org.kie.remote.services.rest.exception.KieRemoteRestOperationException: Organizational entity already exists with [UserImpl:'HR'] id, please check that there is no group and user with same id

Code:
=====================
RuntimeEngine engine = RemoteRuntimeEngineFactory.newRestBuilder()
.addUrl(url).addUserName(userName).addPassword(passWord)
.addDeploymentId(deploymentId).build();

KieSession ksession = engine.getKieSession();
TaskService taskService = engine.getTaskService();

ProcessInstance processInstance = ksession.startProcess("project1.TestProcess");
tasklist = taskService.getTasksAssignedAsPotentialOwner("HR","en-UK");
