Open Graph breaks Structured Data Testing Tool

Question

I added some meta open graph (Twitter, Facebook) to my page, but it breaks my breadcrumb structured data in Structured Data Testing Tool.

I have no idea where http://ogp.me/* coming from. Here is the source code of the page. The page itself. The page in SDTT

If I check the breadcrumb code alone in the SDTT, then it is valid.

Answer 1

This looks like a mix-up on our (Google's) side -- I'll pass it on to the team to check out. Thanks!

Answer 2

When checking your document by entering its URL, it reports this error.
But when checking your document by entering its markup (or when re-checking the code the tool fetched from the URL), it reports no errors.

So this seems to be a bug in the Google Structured Data Testing Tool.

Just a guess, but maybe it’s related to the fact that your last breadcrumb URL is the URL you also make OGP statements about. Anyway, as far as I can see, you wouldn’t have to change anything about your RDFa.
