How to use the raven-js.setUser function in raven-js

function registerRaven (res) {
    if (res.defaults.env.toUpperCase() !== 'DEV' && res.defaults.sentryPublicDSN) {
        const sentryOptions = {
            tags: {

        Raven.config(res.defaults.sentryPublicDSN, sentryOptions).install();
        Raven.setUser({
            email: res.defaults.email || 'anonymous'
        });
        // ES6 loader uses console.error to log un-handled rejected promises
        var originalConsole = window.console.error;
        window.console.error = function () {
            originalConsole.apply(window.console, arguments);
