Couchbase custom deserialization

I have a class that I need to serialize to JSON in Couchbase in a custom manner. So I do something like:

var converters = new[] { new CustomConverter() };
var json = JsonConvert.SerializeObject(myObject, jsonConverters.ToArray()); 
var result = _couchbaseClient.ExecuteStore(StoreMode.Add, id, json);

But how can I deserialize this again, using the CustomConverter? I want to retrieve the JSON and do the deserializing myself. I realize there's a ExecuteGet method, but I'd like to work via a view.

Is this possible?

I've tried add my converter to the JsonConvert.DefaultSettings but it doesn't seem to use it. I keep getting a JsonSerializationException. I'm guessing Couchbase resets the settings, or uses its own.

Digging into the Couchbase code, I found it. Couchbase has some extension methods which use their own settings. You can see this on GitHub:

public static class CouchbaseClientExtensions
{
    public static JsonSerializerSettings JsonSerializerSettings;

    static CouchbaseClientExtensions()
    {
        JsonSerializerSettings = new JsonSerializerSettings
            {
                ContractResolver = new DocumentIdContractResolver()
            };
    }

    // ...

    private static string SerializeObject(object value)
    {
        var json = JsonConvert.SerializeObject(value,
                                Formatting.None,
                                JsonSerializerSettings);
        return json;
    }
}

So you can add your own converters like this:

foreach (var jsonConverter in jsonConverters)
{
    if (!CouchbaseClientExtensions
             .JsonSerializerSettings
             .Converters.Any(x => x.GetType() == jsonConverter.GetType()))
    {
        CouchbaseClientExtensions
            .JsonSerializerSettings
            .Converters.Add(jsonConverter);
    }
}
