OmniOut Issue: Error "unable to authenticate, need: BASIC realm=Sonatype Nexus Repository Manager"

Perform the following actions:

1. Clear the NPM cache using: npm cache clean --force 
2. Confirm the Node.js version in use is v14.16.1 or higher.
3. Validate the .npmrc file within the OmniOut project. This file is not provided by Salesforce Industries (SFI) and depends entirely on the local development environment. A properly configured .npmrc should resemble the example below:
   always-auth=true
_auth=your_token_here
@vlocity-cme:registry=https://repo.vlocity.com/repository/vlocity-public/
@vlocity-cme-sdk:registry=https://repo.vlocity.com/repository/vlocity-public/
@vlocity-ins-sdk:registry=https://repo.vlocity.com/repository/vlocity-public/ engine-strict=true 
4. After correcting the .npmrc file, run: yarn install 

Alternative Method

Authentication can also be completed by running: npm login --registry=https://repo.vlocity.com/repository/vlocity-public/

This method requires the username and password associated with the NPM key.
Once authenticated successfully, npm install should execute without errors.
