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:

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).
