Site is unpublished. I also can’t find where you are using the above code in your site.
I don’t think the API is meant to be “initialized” this way.
Side note, you shouldn’t be using API keys in JS, as anyone can “steal” them and make modifications to your site using that key.
You also shouldn’t be posting the key in the forum (although I have verified that the key works and I can retrieve your site).
