I would like to get some xml-data from a web-address. Unfortunately I always get an erorr...
Access to XMLHttpRequest at 'xxxx' from origin 'http://localhost:3000' 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.
Does anybody now how to fix it? Do I have to call it server-side? If yes, how would I do it?
