CORS Error when hitting from Cloudfront to API Gateway

0

We have added the CDN in front of API gateway, but when we are hitting from the Postman it is working fine, but from Frontend we are getting CORS error when we are passing Headers, in CORS we allowed those headers

Hi,

this article "CloudFront reverse proxy API Gateway to prevent CORS" https://www.rehanvdm.com/blog/cloudfront-reverse-proxy-api-gateway-to-prevent-cors may help you in fixing your issue.

If you want deeper support from re:Post community, you should provide more details about your issue: error messages, config, etc.

    list of api when added with headers that time it is showing cors the header is set('x-api-key', 'xoGxDUvGcI7zzESs15ltz3H4nYzcbHtD17WB2JTz')

                    .set('source', 'Web')

                .set('source-type', this.browserName);

    'x-api-key', source, source-type, Authorization'

    BE will recieve call from gateway only

    its just we lept cdn in front of gateway so if same request raised by FE it will reply from its cache rather than calling gateway again

Postman does not check or enforce cors mechanisms, as that is a browser native feature. Are you handling cors on backend side by allowing origins?
