I am using passing a variable to my process and instantiating the bpmn process like below.
Map<String, Object> variablesMap = new HashMap<>();
// start process model
first stop of the process is a service task and the second task is a human task.
in the human task I wanted to see all the unassigned tasks. for the I have a Spring rest controller with the below mentioned java code.
List tasklist = processEngine.getTaskService().createTaskQuery().taskUnassigned().orderByTaskCreateTime().desc().list();
when I run that spring rest service I am getting the exception.
ERROR org.camunda.bpm.engine.context - ENGINE-16004 Exception while closing command context: execution 29 doesn’t exist: execution is null
org.camunda.bpm.engine.exception.NullValueException: execution 29 doesn’t exist: execution is null
Any thoughts on this would be great help.
