When using the X-Schema-Version request header, this causes a preflight request as expected, but the preflight response is 404.
No issues when not using the header/preflight not required.
Anyone else seeing this or just me?
Been a while without any sort of response, so let me try asking more simply:
Has anyone tried using the X-Schema-Version header instead of the v query parameter? If so, did you get a valid response?
Anet devs, is the server actually configured to respond to HTTP OPTIONS requests for CORS preflight? Custom headers won't work without that.
Preflight requests are not supported (yet) by the API. https://gitter.im/arenanet/api-cdi?at=5738e35f1794136a7d08e560
