Hey there! If you need support, help, or advice then this is not the place to ask.
i have this error in my project, i'm triying to fetch data from an local API linked to a MySQL database developped in Nest.js
(URL : http//localhost:3001/products/[id]) so them when i call the API from another local app (which developped in Reactjs URL: http://localhost:3000/p/1) with Acces-Control-Allow-Origin enable for this URL they show me this error

Thanks !
