Issue
After you migrate your server from LiveCycle 7 to LiveCycle ES 8.2.1, the following error may appear in the log when you submit a task in Workspace:
javax.ejb.EJBException: EJB Exception: : com.adobe.idp.DocumentError: The document pointing to the file "/data/myservermydomain/AdobeDocumentStorage/session_wfattach585520/9084040089345862489" has expired.

Reason
The process itself stalls when this error occurs. The error refers to a task attachment that no longer exists in the DocumentStorage directory. This error can occur if the LiveCycle 7 session referencing the target file was deleted, and LiveCycle 8 references to the target file remained. Deleting the LiveCycle 7 session deleted the session_wfattch…. directory, leaving the LiveCycle 8 references pointing to deleted resources.
Solution
Restore the missing files from a backup of your LiveCycle DocumentStorage directory. Or, delete the source task whose attachments are being copied or delete the attachment itself.
