Reason: CORS request not HTTP
CORS requests may only use the HTTPS URL scheme, but the URL specified by the request is of a different type. This often occurs if the URL specifies a local file, using a file:/// URL.
To fix this problem, simply make sure you use HTTPS URLs when issuing requests involving CORS.
