Running into Cannot find any valid path in operation chain error with Document.GetPrincipalEmails and Notification.SendMail

pegsablaze_ — Fri, 14 Feb 2014 00:08:22 GMT

I am writing a chain to retrieve the emails of assignees for a workflow node, and send an email to those assignees.

My current chain:

Context > Fetch Document
Document > Get Principal Emails (retrieve the assignee emails here)
Audit > Log
Context > Run Script
Document > Set Lifecycle
Document > Set Property
Notification > Send Mail (set the TO property to the assignee emails here)

My chain works fine if I leave out Document > Get Principal Emails (I substitute in a dummy email for testing), but if I run the chain as above, I get the following error stack:

Caused by: org.nuxeo.ecm.platform.routing.api.exception.DocumentRouteException: Error running chain: AssignReview

Any ideas? It doesn't matter where the Get Principal Emails operation is location the chain, it still throws the error.

I am on the latest hotpatch (HF06).
