when trying to send a request (I make a request with vanilla JS) to my Next JS application (I only need the status code of the request) it gives an error about the request being blocked by CORS. How can I fix this? My next application uses Clerk, maybe it is somehow interfering

const response = await fetch(MyUrl, {
    method: 'GET',
});

Of course it's possible to put mode: 'no-cors', but then I can't get the status code prompt, which I really need

when beeing on localhost there won't be any origin headers sent with your request. When deploy there will be origin headers.

How to still have origin headers while beeing on localhost?
Use an extension like: https://chromewebstore.google.com/detail/allow-cors-access-control/lhobafahddgcelffkeicbaginigeejlf
This will add the origin header inside your localhost env
