Description
When getting a document with an empty body, which may happen with LegacyTranscoder with null or empty strings, the operation throws an exception:
Specified argument was out of the range of valid values. (Parameter ‘start’) stack: at Couchbase.Utils.SlicedMemoryOwner1..ctor(IMemoryOwner1 memoryOwner, Int32 start, Int32 length)
at Couchbase.Core.IO.Operations.OperationBase.ExtractBody()
at Couchbase.KeyValue.CouchbaseCollection.GetAsync(String id, GetOptions options)
