Hi,
I am trying to terminate process instance inside its task delegate by calling method: delegateExecution.getProcessEngineServices().getRuntimeService().deleteProcessInstance(delegateExecution.getProcessInstanceId(), "sample reason");
Process is terminated but after a moment I receive an exception:
2023-03-08 14:52:08,214 ERROR [camundaTaskExecutor-2] org.camunda.commons.logging.BaseLogger: ENGINE-16004 Exception while closing command context: Cannot invoke "org.camunda.bpm.engine.impl.pvm.runtime.PvmExecutionImpl.getDelayedEvents()" because "scopeExecution" is null
java.lang.NullPointerException: Cannot invoke "org.camunda.bpm.engine.impl.pvm.runtime.PvmExecutionImpl.getDelayedEvents()" because "scopeExecution" is null
My setup:
Can you help me?
What’s up my friend!
From the informed context, I believe that when activating the “deleteProcessInstance” the instance of the process that is being passed to be deleted no longer exists.
Possibly it has already been deleted, or the process has already been terminated, either by the normal flow, or by some BPMNError flow, and therefore the instance is not in the camunda.
We can handle this in 2 ways… wrapping your code in a “try/catch” to catch the nullpointer error like this:
try {
delegateExecution.getProcessEngineServices().getRuntimeService().deleteProcessInstance(delegateExecution.getProcessInstanceId(), "sample reason");
} catch (NullPointerException e) {
// use to ignore any exception...
}
or you can add a “true” parameter to skipCustomListner at the end of your delegateExecution, as this will ignore any custom listeners that might interfere with deleting the instance.
delegateExecution.getProcessEngineServices()
.getRuntimeService()
.deleteProcessInstance(delegateExecution.getProcessInstanceId(), "sample reason", true);
Hope this helps.

Hi,
thank you for response. I tested your 2 solutions and it doesn’t work for me. I attach whole stacktrace:

Moreover, my method is not in the stacktrace.
Hello dude! \o
could you explain me better why you’re using "org.camunda.bpm.engine.impl.pvm.runtime.PvmExecutionImpl.getDelayedEvents() ?
The correct thing for your case, I believe it would be to use
"org.camunda.bpm.engine.runtime.xxxxxxxx"
"org.camunda.bpm.engine.RuntimeService"
Remember to change “xxxxxxx” in each use case.
using a RuntimeService instance… there is a method that can be called to delete the process instance:
runtimeService.deleteProcessInstance(processInstanceId, deleteReason);
Any doubt, I am available!

I have resolved this problem by creating another subprocess. Thank you!!!
