Reason: CORS header 'Origin' cannot be added
What went wrong?
The user agent was unable to add the required Origin
header to the HTTP request. All CORS requests must have an
Origin
header.
This can happen if the JavaScript code is running with enhanced privileges allowing it access to multiple domains' content, for example.
