Comment 1 for bug 1890574

I found the reason for the error.
A DLO object was uploaded to the cloud storage.
Then the object type was changed to SLO.
But for some reason, the change only occurred on one server.
On all other servers, the object remains DLO.

Currently on the same server:

Only on one server the object became SLO, and on all other servers the object remained DLO
Why did this happen?
