We’re running Couchbase Server CE 5.0.1 cluster and communicate with it using java-client ( https://github.com/couchbase/couchbase-java-client ) in version 2.7.2 to store JSON documents.
We perform document updates using sub-document API ( https://docs.couchbase.com/server/5.0/developer-guide/sub-doc-api.html ) e.g.:
final AsyncMutateInBuilder asyncMutateInBuilder = asyncBucket.mutateIn(createDocumentId(profileId)).upsertDocument(true);
final SubdocOptionsBuilder optionsBuilder = SubdocOptionsBuilder.builder().createPath(true);
asyncMutateInBuilder.upsert(path, value, optionsBuilder)
asyncMutateInBuilder.execute()
During these updates frequently we’re receiving CouchbaseException with cryptic message: NOT_STORED . Example stacktrace:
"error":"com.couchbase.client.core.CouchbaseException",
"stacktrace":"com.couchbase.client.core.CouchbaseException: NOT_STORED at

Is anyone facing similar problem or know what can be the root cause? I was looking in documentation and server logs for any information about root cause of such exception but failed - in server logs I don’t see any corresponding logs and documentation doesn’t provide any explanation/troubleshooting in such cases.
Thanks for any suggestions or explanations!
