We are trying to get oembed content from CVS to Sell CBD Products in 800 Stores in 8 States – NBC New York which is a 404

The thing is, this URL comes from their page source:

<link rel="alternate" type="application/json+oembed"
    href="https://www.nbcnewyork.com/services/oembed/?url=https://www.nbcsandiego.com/news/national-international/CVS-to-Sell-CBD-Products-in-800-Stores-in-8-States-507484191.html"
    title="CVS to Sell CBD Products in 800 Stores in 8 States - NBC 7 San Diego " />

So I would day the bug is from them, not us.
