proxy not working for react and node

I experienced this issue quite a few times, and I figured it’s because of the cache. To solve the issue, do the following

Edit: @mkoe said that he was able to solve this issue simply by deleting the package-lock.json file, and restarting the app, so give that a try first. If that doesn’t resolve it, then do the following.

1. Stop your React app
2. Delete package-lock.json file and the node_modules directory by doing
   rm -r package-lock.json node_modules
   in the app directory.
3. Then do npm install in the app directory.

Hopefully this fixed your proxy issue.
