Google SDTT error: "All values provided for http://www.example.com/ must have the same domain."

Question

When I copy/paste JSON-LD example from Google Documentation (code-snippet below) I get an error in the Structured Data Testing Tool:

http://www.your-company-site.com (All values provided for http://www.example.com/ must have the same domain.)

Why is Google's own documentation example giving an error?

Code snippet from Google’s documentation:

<script type="application/ld+json">
{
  "@context": "http://schema.org",
  "@type": "Organization",
  "url": "http://www.your-company-site.com",
  "contactPoint": [{
    "@type": "ContactPoint",
    "telephone": "+1-401-555-1212",
    "contactType": "customer service"
  }]
}
</script>

Answer 1

It appears the testing tool assumes example.com as its domain.

When testing if you can update your url to "www.example.com" it will validate successfully.

<script type="application/ld+json">
{
  "@context": "http://schema.org",
  "@type": "Organization",
  "url": "http://www.example.com/",
  "contactPoint": [{
    "@type": "ContactPoint",
    "telephone": "+1-401-555-1212",
    "contactType": "customer service"
  }]
}
</script>

Answer 2

This error started appearing somewhere in the month before your post. Since the error disappears when the "contactPoint" is left out, even though it doesn't contain an URL, this is most likely a bug in the validation tool.

I came across the same problem and asked about it on the support forum.
