I tried the procedure I read on Couchbase to resolve conflicts Resolving Conflicts, sync-gateway 1.5.
From couchbase-sync-gateway I get a result from _bulk_docs, this error but I can't find any feedback:

The error is "Failure adding Rev to RevTree", I understand what happened but I can't fix it.
UPDATE: 15.09.2019
The response of bulk_docs with CRUD key log:

Only one revision didn't go well, I think I have three revisions into the Bodymap of the same document and one of this its body is like:
[...]
8: "{\"_deleted\":true}",
[...]
Status of the document:
[...]

the offending revision is present in the RevTree. I don't understand where the problem is.
UPDATE 16.09.2019
I think I understand what happens in Couchbase & Sync-Gateway: a document has forked in two documents, one 3-XYZ, and 4-QWE. The two documents are equal but differ from the revision id. When I call the bulk_docs 4-QWE become 5-IOP, and 3-XYZ become 4-QWE. But the 4-QWE is already presenting in RevTree, error 500. It's what I think, anybody agrees?
UPDATE 20.09.2019
The error has disappeared. I added a new field in the document what I save in the bulk docs. The bulk_docs works properly but the conflict also remains the Bodymap. Do you know any solutions?
There are 3 possible scenarios you could get this error:
The particular error you're hitting should be logged, if you enable the CRUD log key: https://docs.couchbase.com/sync-gateway/1.5/config-properties.html#logging-default-logKeys
That should give you a hint as to what is going wrong.
