The attachments folder is missing during the import.
ソリューション
Since this happens when the attachments folder is missing before the import process starts, what you'll need to do is to get your attachments folder from OD (if you had them imported separately from the data) and then move the attachments into Confluence Server's attachments folder. Once this is done, proceed with the import as usual.
