I have created server with npm init colyseus-app ./my-colyseus-app and clientside with Client-side SDK/Installation/Defold Engine topic from documentation.
Client throws an error attempt to call method 'loop' (a nil value). It means that client object (which creates with ColyseusClient.new) is not nil, but not contains loop method. It may be due to connection error, but method MyRoom/onCreate on serverside is working. But MyRoom/onJoin is not. And callback of join_or_create on client side is not working (even with an error). No errors are displayed. NodeJS, Defold, Colyseus are fresh version.
