Catching Technical Errors from a Task

[sg02.aug]

Hi Guys,

I am quite new to Camunda.I am trying to create a project in which it will throw the Business Errors from the Task Listener and catch it from the same task where that listener was invoked.
I used an Error Boundary Event task to implement this but the issue is when that task is catching the error from listener ,its retrying the task to execute again and again.
What i want is it should not retry at all and just throw the error to the user.
Please help me in this.

Thanks & Regards

(no need for the gateway in this case) public class CustomTask1Listener implements TaskListener { @Override public void notify(DelegateTask delegateTask) { try{ // your business code goes here } catch (Exception e) { throw new ProcessEngineException("Error!!!"); } } } If you prefer to explicitly model the error then you can attach error boundary event to the task and …

Hi @sg02.aug,

Throwing a ProcessEngineException from within a TaskListener shouldn’t create an incident.

Hi @sg02.aug,

here is an example how to throw a BpmnError form an execution listener: GitHub - camunda-community-hub/Make-Rest-Calls-From-Camunda-Example: This is an example application which
