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.

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.
