Getting 400 Bad Request

Hi Folks,

I have parallel stages for “Success” event from gateway, but I’m stuck with message correlation.

camunda url: http://localhost:8080/engine-rest/message

"messageName" : "Success",

"businessKey" :"79547153"




"type": "RestException",

"message": "org.camunda.bpm.engine.MismatchingMessageCorrelationException: Cannot correlate message 'Success': No process definition or execution matches the parameters"


I’ve tried a few techniques that were suggested in this forum, but still no luck.
what is wrong with my process?

Thanks in advance.

Can you upload your model?
Can you also share how you’re starting the process instance.
