wayneloftus commentedI am seeing the same issue.
As it turns out, the constant JSON_UNESCAPED_SLASHES is only available after PHP 5.4.0 http://php.net/manual/en/json.constants.php#constant.json-unescaped-slashes. You might check your PHP version. If you're like me, your architecture has you stuck at 5.3.3. Thanks Red Hat!
Removing it does make the urls look a bit odd (e.g., 'https:\/\/\drupal.org\/project\/structured_data'), but double-checking in Google's Structured Data Testing Tool, it interprets the escaped urls correctly: https://developers.google.com/structured-data/testing-tool/
Above is a patch which checks to see if the constant exists before using it.

Fixed.
