Event registry start - error

Hi, I have a problem with Event registry start. My flowable app is listening RabbitMQ broker. When I see the rabbitmq console I can see the consumer working:

But, the problem is when I post a event to rabbit, flowable doesnt initialize a process instance. The flowable logs show the following output:

2020-12-10T14:24:42.409511975Z Caused by: org.flowable.common.engine.api.FlowableObjectNotFoundException: no event definitions deployed with key ‘3’

I dont understand why flowable is tring to search event definition with that key (3). In the model I set the following:

the event key is:

Best regards and thank you for your help

Hi xaviercocco, was there any solution to this item?

For a Flowable product evaluation I tried to implement this example: Introducing the Flowable Event Registry – Flowable Blog to test how useful is Flowable’s event registry.
So after configuring ports in application.properties my app is listening to a Active MQ instance, and both systems MQ and Flowable know each other now. My deployed model has set following attributes:

Name : Start Event
Event key : startEvent
Event name : Start Event
Mapping from event payload (event property - variable): customerId - customerVar, productNumber - productNO
Channel key : testChannel
Channel name : Test Channel
Channel type : jms
Channel destination : testQueue
Event key fixed value : myEvent
Event key json field : myEventField
Event key json pointer : myEventPointer

As soon as I send the suggested sample message into my Active MQ testQueue
“customerId”: “123455”,
“productNumber”: “flw123”
following, very similar error message occurs in the Flowable log (and no task is initiated in Flowable):

2021-11-16 08:34:07.547 WARN 25864 — [1#testChannel-1] o.s.j.l.DefaultMessageListenerContainer : Execution of JMS message listener failed, and no ErrorHandler has been set.

Any ideas here?

Same problem here but i figured it out it seems:
“Event key fixed value” must be equal to “Event key” to start the process.
Hope this helps

Hi Xavier,
Can you also look at your event subscriptions in Flowable Control.
You can find it just underneath the Processes or Cases section in Control.
Also look at the “Event Key” detection element in you Inbound Channel definition.
It’s possible this is where the 3 is coming from.
