The attribute image.itemtype has an invalid value

Question

I am using JSON-LD format for Structured data. In home page @type=website & in details page @type=Article. Logo property of Organization section in details page showing following warning in Google Structured Data Testing Tool But home page is not although in both page value is same.

http://kothaboli.com/media/1018/ka.jpg (The attribute logo.itemtype has an invalid value.)

Answer 1

If you want Google’s Article rich result, you have to provide an ImageObject value (with url/height/width) for the logo and image properties. Currently you provide a URL value.

If you don’t want this feature (or you can’t get it because you can’t provide other required properties), you can keep your structured data like that.
