Using IYamlTypeConverter, what's the correct way to emit a null value?

[Cyberboss]

I'm trying to serialize System.Uri as a string. My implementation of WriteYaml currently looks like this.

		public void WriteYaml(IEmitter emitter, object value, Type type)
		{
			if (emitter == null)
				throw new ArgumentNullException(nameof(emitter));

			CheckSupportsType(type, true);

			var uri = (Uri)value;
			emitter.Emit(
				new Scalar(
					uri.ToString()));
		}

However, when value is null I'm not sure what the correct Scalar to emit is. Emitting null or new Scalar(null) has only resulted in errors. I would like the resulting YAML field to just be left blank, i.e. ControllerAddress: \n. How would I accomplish this?

I managed to find a workaround with [YamlMember(SerializeAs = typeof(string))]
