Hi Mustufa,

This is a classic CORS (Cross-Origin Resource Sharing) issue. In Odoo, you’ll need to enable CORS headers on your server.

If you’re running Odoo behind a web server like Nginx, add something like:

nginx
CopyEdit
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';
add_header Access-Control-Allow-Headers '*';

Or, if you’re using Odoo’s built-in server, look into middleware solutions or a proxy to inject CORS headers.

Also, check that your API route allows OPTIONS preflight requests and responds correctly.

Hope this helps!
