Link.js:27 Uncaught TypeError: Cannot read property '0' of null

I’m getting this error which also seems to be causing my paginated table to not work properly (it loses all data on sort or page change)

link.js:27 Uncaught TypeError: Cannot read property ‘0’ of null

It looks like it might have something to do with routing??

link.js27

update: function(props) {
if (props.href != this.props.href) {
var url = this.props.href;

        if (url[0] == '.' && url[1] == '/') {
            var base = document.querySelector('meta[name="ac:base"]');
            var route = document.querySelector('meta[name="ac:route"]');

            if (route && route.content) {
                var path = route.content;

                if (base && base.content) {
                    path = base.content.replace(/\/$/, '') + path;
                }

                var match = dmx.pathToRegexp(path, [], { end: false }).exec(location.pathname);

                if (match) {
                    this.$node.setAttribute('href', url.replace('./', match[0].replace(/(\/+)?$/, '/')));
                    this.routeLink = true;
                    return;
                }
            }
        }

        if (url[0] == '#') {
            this.routeLink = true;
        } else {
            this.routeLink = false;
        }

        this.$node.setAttribute('href', url);
    }

    this.set('active', this.isActive());
},

Any ideas would be welcome. Thanks.
