I'm stuck on something.
While I'm trying to fetch a sign-in in LocalHost I got an error on my browser console
my fetch code here :
when I fetch With POSTMAN everything is working perfectly.
I Also add a proxy line on my package.json file and what I don't understand is the error above is trying to fetch on localhost:3001 but my proxy line is :
"proxy": "http://localhost:3000"
any help appreciated !
