The type it indicates isExpected an image media type but got "text/html; charset=utf-8" instead
, however, from the documentation, it seems that both the twitter:url and the og:url are supposed to provide the canonical url for the page on which the meta tag appears, so that if the page is shared, the true, canonical page's content is referenced.meta twitter:url
The validator seems to think it should be a URL to an image. Is this a bug?
