Error: Illegal wire type for field Message.Field #28

Closed fean closed 9 years ago

I'm trying to control our Styled Media Receiver with your CASTV2 module for NodeJS. It has been very easy to implement so far. But right after I launch the receiver application the following error occurs:

Error: Illegal wire type for field Message.Field .extensions.api.cast_channel.CastMessage.payload_type: 5 (0 expected)
    at Error (<anonymous>)

After that error message it goes on about some other errors about groupings. This is the code I used:

var Chromecast = require('castv2-client').Client;

function connectChromecast(name, service) {
    var client = new Chromecast();

    client.connect(service.addresses[0], function() {
        console.log('Connected to ' + name);
        client.launch({
            APP_ID: '[Our App ID]'
        }, function(err, app) {
            console.log(name + ' is ready to cast.');   
        });
    });
}

The first parameter of launch is a sublcass of Application. For a styled media receiver it would be a subclass of DefaultMediaReceiver with another APP_ID.

Or follow the example and do something like that before launch : 

DefaultMediaReceiver.APP_ID = '[YOUR APP_ID]';

But i'd suggest subclassing DMR, it would be much cleaner :)

Thanks for responding this quickly. Well that actually makes sense ;)

I'm going to test it right now. If that lifts the problem I'l close the issue right away!
