Error Message

The assertion failing for this test is: 

Root Cause

The deserialization of the document spec into DocumentMetadata is failing (https://github.com/couchbase/couchbase-net-client/blob/5a8a04e0b046a20dc9b4b91bbff564ee9d89335b/src/Couchbase.Transactions/DataAccess/DocumentRepository.cs#L195).

This is due to the MetadataSerializer being passed in the LookupInOptions through the Serializer field, instead of passing in a Transcoder(Serializer) in the options. LookupInResult.ContentAs<T> uses the Transcoder's Serializer to deserialize content.
