[mvictorl]

What to do?

D:\workspace\examiner\client>npx create-react-app .
...
D:\workspace\examiner\client> yarn start
yarn run v1.22.4
$ react-scripts start
(node:1484) [DEP0148] DeprecationWarning: Use of deprecated folder mapping "./" in the "exports" field module resolution of the package at D:\workspace\examiner\client\node_modules\postcss-safe-parser\node_modules\postcss\package.json.
Update this package.json to use a subpath pattern like "./*".

[cybersaksham]

Go to the postcss package in the node-modules folder of your directory
Basically, go to the D:\workspace\examiner\client\node_modules\postcss

You will find a file package.json.

Open that file and search for the field exports

In exports field change "./": "./" to "./": "./*"

This is the issue in postcss package.
