A cross-origin resource sharing (CORS) request was blocked because it contained request headers that were neither CORS-safelisted (Accept
, Accept-Language
, Content-Language
, Content-Type
) nor allowed by the Access-Control-Allow-Headers
response header of the associated preflight request.
To fix this issue, include the additional request headers you want to use in the Access-Control-Allow-Headers
response header of the associated preflight request.
