I have created a sample apache camel swf application based on Spring Boot. It works as expected for the first activity but even though it seems to schedule the second activity, the activity does not get invoked.
Reference to sample application - https://github.com/kpkurian/camel-aws-swf-shopping-cart-wf
The log shows below line
2018-01-18 00:23:32.705 DEBUG 9456 --- [erMasterQueue 1] o.apache.camel.processor.SendProcessor : >>>> aws-swf://activity?activityList=&amazonSWClient=%23swfClient&domainName=name&eventName=<2nd activity name>&version=5.0
The history shows 2nd activity is not scheduled. I can see the WorkflowExecutionCompleted event in the end.
