[MonoV2] Event listeners with a byte[] as a parameter fail to register

[ruigouveiamaciel]

What happened?

Events that take byte arrays as a parameter fail when registering (past build 8380).

public class ExampleServerScript : BaseScript
{
	[EventHandler("exampleEvent", Binding.Remote)]
	private static void HandleIncomingRequest([Source] Player player, byte[] data)
	{
		Debug.WriteLine("Hello World");
	}
}

Expected result

Event should not fail to register

Reproduction steps

1. Use build 8385 of FxServer

2. Make a resource that uses MonoV2

3. Add this script to your resource and watch the server/client fail to register it

public class ExampleServerScript : BaseScript
{
	[EventHandler("exampleEvent", Binding.Remote)]
	private static void HandleIncomingRequest(Player player, byte[] data)
	{
		Debug.WriteLine("Hello World");
	}
}

Try again on latest build.

This was already solved with the msgpack reverted
