I am trying to send information back up from a child workflow process to the parent process. I followed the Process Buider Best Practices Guide to use HTTP Outbound and HTTP Inbound activities, but I get the error I'm showing below. Note that I have a Post Event to Parent activity in the child process and the HttpInbound activity in the parent has a trigger set to wait for the event. Any ideas on this?
java.lang.RuntimeException: Error occured while executing a HttpMethod. Status code: 500 Response: HTTP Request Processed failed: Workitem for workflow: 4d01d93580007931 is not in the required state
