Map<String,Object> variable= new HashMap<>();

variable.put(“testPlan”, “testPlan”)
runtimeService.startProcessInstanceById(key,variable);

Hello @Mithun_Shetty,

Please share your java file where you are trying to start the process instance by id.

Thanks,

4

Map<String,Object> variable= new HashMap<>();

variable.put(“testPlan”, “testPlan”)
runtimeService.startProcessInstanceById(key,variable);

I see this issue when in the model I enable asynchronous before for the start event

5

Are you using multiple engines? Could you share your process model as well ?

6

call.bpmn (10.5 KB)

if i uncheck asynchronous on start event, works fine i dont see any exception

7

I don’t have access to your rest endpoints that you call in the process. Could you share your project?

8

I am really sorry, I am not able to share them here entire project, below is the snapshot

@Override

public CtmOutGoingCallTestCase createAndAddCallObserver(String id ) {

runTimeService.setVariable(id, “CreateAndCallObserver”, “true”);

log .info("OutGoingCallTestCaseServiceImpl -> createOrAddCallObserver : Create/Add call observer successfully ");

return null ;

}

@Override

public CtmOutGoingCallTestCase makeCall(String id) {

String orderId=(String) runTimeService.getVariable(id, “CreateAndCallObserver”);

String aVariable=(String) runTimeService.getVariable(id, “testPlan”);

runTimeService.setVariable(id, “CreateAndCallObserver”, “false”);

System. out .println(orderId+" "+aVariable);

log .info(“OutGoingCallTestCaseServiceImpl -> makeCall : Placed call successfully”);

return null ;

}

@Override

public CtmOutGoingCallTestCase terminateCall() {

log .info("OutGoingCallTestCaseServiceImpl -> terminateCall : Terminated call successfully ");

return null ;

}

@Override

public CtmOutGoingCallTestCase cleanUp() {

log .info("OutGoingCallTestCaseServiceImpl -> cleanUp : Clean up done successfully ");

return null ;

}

also i am getting below error “message”: “Type definition error: [simple type, class org.camunda.bpm.engine.impl.pvm.process.ProcessDefinitionImpl]; nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Direct self-reference leading to cycle (through reference chain: java.util.ArrayList[0]->org.camunda.bpm.engine.impl.persistence.entity.ProcessDefinitionEntity[“processDefinition”])”,

when i try to get process definition using below code
repositoryService.createProcessDefinitionQuery().list();

can you please help me out, need to finish in this as we need to demo

Thanks @Mithun_Shetty ,

Using connectors: Using connectors come in handy if you want to easily make rest calls and use the modeler to do so. However, if a connector call fails (ie restendpoint down or failure to set a variable by the rest endpoint) such error won’t be caught by Camunda. So you need to make sure to check the response from the rest endpoint. If there is an error you can retry or set the retries to zero to throw a technical error which you can later see in cockpit. You could also throw a BPMN error eventhough this is meant for business errors like this [REST-API] Service Task Error Handling.

Your process: I managed to succesfully deploy a similar setup as per your process and rest endpoints and I was able to execute everything correctly. I did not get any errors. I am starting to think that there might be something wrong with your environment. Can you share your POM? Also, I see that you are trying to set and get variables with your rest endpoints. Have you considered doing this by using Java Delegates with Camunda like this https://docs.camunda.org/get-started/java-process-app/service-task/?

Also, sorry that you are in a rush to do a demo. What type of demo are you trying to do? Are you trying to showcase Camunda?

Regards,

When you copy code or logs should follow the below steps referred in this how-to-format-code-blocks, it could be clear and readable.

Also refer various markdowns to format code blocks here.
