Issue/Introduction

I am currently facing issues to XOG out attachments for few ideas. Note that not all Ideas are having this issues. Only few but would like to know the reason as I expect there might be more. Below warning seen in the XOG output file:
XOG-9100: Failed to export document(s) on object type: idea, ObjectID/Name=ID-XXXXX

Cause

One of the files attached to the idea instance could not be opened, after reviewing app-ca.log log it was identified that file did not exist in the filestore.

Environment

SaaS

Resolution

Removed the document that was missing in filestore via UI and after that other documents were successfully XOG out with the instance.
