//this is called to push messages onto ASQ from the browser
sendMessage(queueKey, message) {

        let json = this.orderedJsonStringify(message);
        let encodedMessage = btoa(json);
        let url = this.tokens[queueKey]; //this is the url for the queue including SAS token for auth. This is stored in a JWT token created at login

        this.fetch(url,
            {
                method: 'post',
                body: `<QueueMessage><MessageText>${encodedMessage}</MessageText></QueueMessage>`
            })
            .then(response => console.log("ok"))

    }

ASQ expects to see a MessageWraper. The message you're sending is not MessageWrapper I presume. So how does it work?...
