You may find Google’s structured data tool reports the error:
(The attribute logo.itemtype has an invalid value.)
For some reason, the logo attribute a publisher of a NewsArticle doesn’t take a straight url like Organization does. As such, what you need is similar to this:
“logo”:{“@type”: “ImageObject”,”url”: “https://example.com/image.jpg”}
Hope this helps!
