Local build PCF/Portal - When using npm watch or npm build you can get error - [ 'error:03000086:digital envelope routines::initialization error' ]

[JanKrupicka]

Sometimes in your life you might come across this error.

It happens during npm build or npm watch.

Common error

[ 'error:03000086:digital envelope routines::initialization error' ]
ERR_OSSL_EVP_UNSUPPORTED

Cause

The reason this is happening is that you can only use Node JS version 16.x.x.x to run the portal.
If you have a higher or lower version LOL good luck boy.

But the real root cause of the issue is in webpack v4 which stopped working in Node.js because the new OpenSSL 3.0 does not support crypto algorithms.

Troubleshooting Steps

1. Install https://github.com/coreybutler/nvm-windows
2. Open PowerShell terminal
3. Use command "nvm install 16"
4. Use command "nvm use 16"

And you should be done.

FYI I found this on stack overflow:

Danger
This question has more than 30 answers, most suggesting to either downgrade Node.js to pre v17 or to use the legacy SSL provider. Both of those solutions are hacks that leave your builds open to security threats.

Reason For The Error
In Node.js v17, the Node.js developers closed a security hole in the SSL provider. This fix was a breaking change that corresponded with similar breaking changes in the SSL packages in NPM. When you attempt to use SSL in Node.js v17 or later without also upgrading those SSL packages in your package.json, then you will see this error.

The Correct (safe) Solution (for npm users)
Use an up-to-date version of Node.js, and also use packages that are up-to-date with security fixes.

You can first try an update to see if that solves the problem:

npm update
If that is not enough, for many people, the following command will fix the issue:

npm audit fix --force
However, be aware that, for complex builds, the above command will pull in breaking security fixes that can potentially break your build.

I ran npm update and it solved my issue.
