Hi, 

I created a process that uses messaging start and end events for communication, integrated it with Knative Eventing and tested the functionality - which works as expected. 

Now I'm trying to incorporate the functionality of throwing and catching intermediate message events. When doing so, the first (throwing) works as expected, but when trying to catch an event I get the following error:

2021-07-06 13:43:32,134 DEBUG [org.kie.kog.eve.imp.CloudEventConsumer] (executor-thread-1) Received message without reference id, starting new process instance with

I see there's a log mentioning the message was received without a reference id, but I did include the process instance id as a cloud event header, as well as the same value for the ce-kogitoreferenceid header. 

What is the right way to send the cloud event including a reference id so that it does not look for a start node that matches the trigger, but matches the reference id to the running process and uses it to send the triggering signal for that intermediate event?

Thanks,
C

Hi Constanza!

Many thanks for trying Kogito with Knative. I think the header for the Kogito reference id extension is wrong. Try "kogitoprocrefid"

We changed these names a while back to align with the CloudEvents spec. Unfortunately, the documentation hasn't been updated yet. I'll fix this tomorrow.

Thanks!

Thank you, Ricardo!

I tried adding the ce-kogitoprocrefid instead of the ce-kogitoreferenceid I was using previously, you can check below, but I still get the same output.

Hi Constanza,

It might be a bug, do you mind sharing a reproducer so I can take a look?
