Null Reference Exception by button click

[rktherk]

Dear Ooui Team,

ive bind over XAML a Button via a Command, as it do not work, so i bind over x:name the button to a click method. Same error its happen. The error in my Debugger console on Chrome is:

Failed to process received message: Newtonsoft.Json.JsonSerializationException: Error getting value from 'MessageType' on 'Ooui.Message'. ---> System.NullReferenceException: Object reference not set to an instance of an object.

thrown in mono.js

i use VS Studio 2017 and the newest (released) nuget packages for .net Standard and Xamarin.Forms.

The over bindings and Code behind Systems work for me. Just the Command pattern seems to be buggy.

Did you manage to get this working? i'm getting the same error, simply trying to run basic ooui.forms example with button click.
