Invalid root for alerts payload

[bzurkowski]

After deployment in testbed, alerts dashboard fails with error:

TypeError: Cannot read property 'map' of undefined
    at Alerts.js:26

Code:

  loadData() {
    axios.get(process.env.REACT_APP_BACKEND_HOST + '/v1/alerts')
      .then((response) => {
        const alerts = response.data.alerts.map(alert => {
          alert.updated_at = new Date(1000 * alert.updated_at);
          return alert;
        });
...

There is no alerts root in alerts payload:
