Hi @tedcha,
I don’t see a reference to a folder error in the recent diagnostic activity. It may have rolled off.
Can you tell me the name and path of the folder?
What action are you taking and on what folder when you see the error message?
Usually a folder/file will not show up within the desktop client if it contains an ignored or illegal pattern. See https://docs.odrive.com/docs/sync-changes#section--ignore-list- and Why are some of my files/folders missing from odrive? (Google Drive and others)
Can you also trigger the error once more and then send a diagnostic immediately after?
