express-jwt | connect/express middleware that validates a JsonWebToken | Authentication library

I am working on a register user setup in React JS, installed crypto library from to secure passwords but when I run the program , it gives me an error :

ERROR in ./node_modules/jwa/index.js 5:13-30

Module not found: Error: Can't resolve 'crypto' in 'E:\Node Tutorial\registerSetup\client\node_modules\jwa'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default. This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:

• add a fallback 'resolve.fallback: { "crypto": require.resolve("crypto-browserify") }'
• install 'crypto-browserify' If you don't want to include a polyfill, you can use an empty module like this: resolve.fallback: { "crypto": false }

Here is my package.json file :

I have a app that is currently deployed on heroku and working perfectly fine. I created a new heroku app and tried to run the same branch. I installed nodejs and all the configuration is the same but for some reason the build is failing at heroku-postbuild: "ng build --prod". It works fine on the previous instance I have on heroku but wont work on the new one. I don't know what i am missing as the information on the error is minimal. I am attaching my package.json as well as the error message I get. any help will be appreciated and let me know if you need me to upload anything else.
