so i shouldn't be adding cors headers to my nginx config?

either way i added them and it still errors for me.

        add_header 'Access-Control-Allow-Origin' '*';
        add_header 'Access-Control-Expose-Headers' '*';
        add_header 'Access-Control-Allow-Headers' 'Authorization,*';
        add_header 'Access-Control-Allow-Methods' 'GET, PUT, DELETE';

Nostrudle says: 

Cannot read properties of undefined (reading 'url')

when I try to upload an image.
 

 Pls Open up web dev tools in browser, open network console and network tab, let me see raw errors, ty sir we'll fix it

Also double check you set the new blossom_path .env per the example .env 

 i fixed it. i removed the upstream server's headers.

        proxy_hide_header Access-Control-Allow-Origin;
