CloudFront has been blocked by CORS policy

I use axios to get a resource (md file) from my cdn (served by aws CloudFront).

I get this error message in the browser:

Access to XMLHttpRequest at 'https://next.cdn.example.com/foo/bar.md' from origin 'https://next.example.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource

My website is: https://next.example.com
My cdn: https://next.cdn.example.com

But in CloudFront I setup everything to support CORS (in the pictures).

What else can I do to solve this problem?

I do believe you need to allow also OPTIONS request on your behavior setup of the CloudFront. OPTIONS request is sent prior to actual GET/POST request for CORS request, see https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#Functional_overview for more details.
