Error Fetch method POST localhost in reactJS

Question

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 !
