    Unable to retrieve process instance variables [kie-server-client version: '6.5.0.Final']

    kishore e Newbie

      Trying to read process instance variables. Both are failing

       

      processServicesClient.getProcessInstance(containerId, processInstanceId, true)

      and

      processServicesClient.getProcessInstanceVariables(containerId, processInstanceId)

       

      Code seems to call http://localhost:8180/kie-server/services/rest/server/containers/test/processes/instances/6/variables

      with error

       

      No error while calling

      http://localhost:8180/kie-server/services/rest/server/containers/test/processes/instances/6

       

       

      kie-server-client. version: '6.5.0.Final'

       

      Solution:

       

       

      queryServicesClient.findProcessInstanceById(processInstanceId, true).getVariables()

          From my tests, these APIs work without problems:

              Map<String, Object> variables =

              processServicesClient.getProcessInstanceVariables(CONTAINER, 98L);

           

          Did you set up the "extraClasses"?

           

          config.addExtraClasses(extraClassList);

           

          Please, provide the error stack trace.

            processClient.getProcessInstanceVariables(containerId, processInstanceId);

              QueryServicesClient.findProcessInstanceById(processInstanceId, true).getVariables() seems to work though.

                Is it possible that you started the process thru the workbench e now you are trying to get variable thru the kieserver?
