Scenario :
1.Once module got request ,we started the process normally and there is some wait signal for call back trigger from other module/application.
2. Once we get the async call back from  module/application we are fetching the corresponding process instance and signals from processInstanc and eventtypes bpm table. And start continuing the process.

Here we are getting the signals but during  processService.setProcessVariables(Long.parseLong(processInstanceId), processVariables) execution getting above exception.

after some few minutes if we trigger ame call back request manually process will continue with success response.

Kindly help!!

Thanks &Regards,
Jeevan
