HistoryProcessInstance not working in activiti 7.0.0.GA

[akash7]

we have upgrated activiti to 7.0.0.GA but the 'historyService.createHistoricProcessInstanceQuery()' is not fetching history process. We are getting it correctly in activiti 6. Would you please suggest, is there any changes to get history process in activiti 7.0.0.GA? Thank you.

this.historyService.createHistoricProcessInstanceQuery().finished()
        .orderByProcessInstanceStartTime().asc().includeProcessVariables()
        .list().parallelStream()
        .collect(Collectors.toList());
