web cors error

[goodmirow-1]

Hello, I am using this sdk very well.

However, due to the cors policy, related data cannot be received normally on the web.

In nginx, the error "No 'Access-Control-Allow-Origin' header is present on the requested resource.", even though the 'Access-Control-Allow-Origin' command allows the cors.

I tried to resolve it using the coursesProxy parameter and header parameter provided by sdk, but I don't know how to use it for normal use.

Are there any good examples?

Hi @goodmirow-1 no, not really. CORS is CORS, nothing we can do on a web from the frontend.. I have read about proxies hence added some fields, but free ones I tried never worked for me. For previews to work on web, they should be parsed on a backend (like https://www.linkpreview.net or something) and not on frontend.
