I am writing you because I have a problem with the Structured Data. I am working now on SEO of the website so it is a big issue.
The problem is that as the last breadcrumb doesn’t have the URL because it is a current page, it miss the url (“@id”) tag on the Structured Data previously known as the Rich Snippets.
I attached the result of an official google structured data test tool. Again it is really big issue for the SEO.
