Error when reading document on Couchbase Server 6.5

I’ve upgraded the Couchbase Server from 6.0.1 to 6.5 recently. During the update, it failed for some reason. I had downgrade it and upgrade again. After finishing the process properly this time, I realized that the Sync Gateway started to show me some errors and when I looked on the admin tool on the browser, it was saying that some documents weren’t found, even though the reference is there.

It’s interesting that I can query these documents (ie query by the type property), but I cannot display any information about then, other than the ID. And looking the ID I found out that the ones that the problem is happening are like: “\u0000[DocID]”, when it shouldn’t have this “\u0000” character.

Is there a way to solve this inconsistency?
