CORS X-authentication problem

Former Member over 4 years ago

Hello Everyone,

I am having a problem with making a request to get all documents in a vault. Every time I pass the x-authentication header in the request, it returns an error

"access to fetch at '172.16.2.29/.../115' from origin 'http://localhost:5500' has been blocked by cors policy: request header field x-authentication is not allowed by access-control-allow-headers in preflight response"

I already have CORS enabled in my IIS Server.

I don't know what causes the error. The image below is my code

It's possible (advisable?) in CORS to restrict the available HTTP headers. It seems that X-Authentication is not one of the allowed ones.

You need to cross-check your CORS configuration and either add this header or maybe just provide a wildcard instead (www.geeksforgeeks.org/.../).

Regards,

Craig.

Hello, Sir

I was able to fixed it by adding the entry Access-Control-Allow-Header:x-authentication and method OPTION in Access-Control-Allow-Methods.

Thanks for your the help! :)
