OnAuth Return CustomData

Hi all,
The OnAuth method can only return the false value,right? What should I do if I want to return custom data after a validation failure？
Thanks.😁

for example:

 onAuth(client, options): Promise < any > {
    return new Promise((resolve, reject) => {
        let myData = {
            code: -1,
            reason: 'token is missing'
        }
        reject(myData);
    });
}

//other test
onAuth(client, options): Promise < any > {
    let myData={
        code: -1,
        reason: 'token is missing'
    }
    return myData;
}


//and the client side
client.joinOrCreate("test").then(room => {
}).catch(err => {
    //the err is null str
});

Hi @BlueBang, currently you can only throw an error containing a string to be able to catch in the client-side.

e.g.

onAuth(client, options) {
    // ...
    throw new Error("token is missing");
}

There are plans on supporting code + reason soon, though: https://github.com/colyseus/colyseus/issues/317

@endel yeah,Because it is still necessary to distinguish between system exceptions and business exceptions. My current solution is to add a formarter in the client-side.tanks for reply.😁
