Tidal Resolver Issue

[LivingWithHippos]

I have Tomahawk 0.8.4, tried with both the nightly .axe and the old .js plugin, when I add my credentials I get

12:13:09 [0]: JAVASCRIPT: "/home/user/.local/share/Tomahawk/manualresolvers/tidal/content/contents/code/tidal.js:1" "TypeError: 'undefined' is not a function (evaluating 'Tomahawk.resolver.instance.saveUserConfig()')" "undefined"

and If I restart Tomahawk

12:08:50 [1]: Hooking up resolver: "/home/user/.local/share/Tomahawk/manualresolvers/tidal/content/contents/code/tidal.js" true 
12:08:50 [0]: JSResolver::JSResolver(const QString&, const QString&, const QStringList&) Loading JS resolver: "/home/user/.local/share/Tomahawk/manualresolvers/tidal/content/contents/code/tidal.js"

line 103 is in the init function

    init: function () {
        var config = this.getUserConfig();
        log(this);

        this._email = config.email;
        this._password = config.password;
        this._quality = config.quality;

        if (!this._email || !this._password) {
            Tomahawk.PluginManager.unregisterPlugin("linkParser", this);
            //This is being called even for disabled ones
            //throw new Error( "Invalid configuration." );
            Tomahawk.log("Invalid Configuration");
            return;
        }

        Tomahawk.PluginManager.registerPlugin("linkParser", this);

        this._login(config);
    }
