When I used "npm run prod" to build npm it shows the following error. Please guide me to solve the problem.

ERROR in ./node_modules/jsonwebtoken/sign.js 6:57-74
Module not found: Error: Can't resolve 'crypto' in '/var/www/html/inb-platform/node_modules/jsonwebtoken'

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 }

Also having a problem with this error message!

This is a problem with webpack 5 not anymore including polyfills for node core modules by default.

Either include the polyfills yourself, or look for a library thats intended to be used in the browser. If you just want to verify Tokens, your best bet is probably: https://github.com/auth0/idtoken-verifier.
