Web-push unknown problem, WebPushError "Received unexpected response code" 400

Question

During development web-push with GCM and chrome. I ran into this problem recently (a couple of hours ago everything worked fine)

I'm not sure if this is due to some changes in GCM or cloud outages ... Any information would be appreciated.

My code

var payload = JSON.stringify({
    title: 'notification title',
    body: 'message body'
});
webPush.sendNotification(params.endpoint, {
    userPublicKey: params.userPublicKey,
    userAuth: params.userAuth,
    payload: payload
}).then(function (res) { 
    // console.log of stuff
})
.catch(function(error){
    console.log(error);
    process.exit(1);
});

Trace:

Answer 1

@Lihn, paste your payload here. From the error message, it looks like you are sending the wrong json message.

GCM docs , 400 , json .
