Fetch issues

Hi guys I’m starting with Frontity but I can’t make it right, right now I’m trying to add the URL of my website to the frontity.settings.json, I added the URL of my website like this

{

  "name": "@frontity/wp-source",

  "state": {

    "source": {

      "url": "http://motion-dev.com/",

      mode: 'no-cors'

    }

  }

},

however I’m getting some errors and I don’t know where it is failing.

The error is the next one

Uncaught (in promise) TypeError: Failed to fetch
