Currently learning Vue js and express js through some tutorials, I am still newbie regarding these technologies.

Anyway following the tutorials I am building a small project in which I have a folder "Client" that contains the frontend side of the project and another folder "Server" that contains the backend.

Just before pushing commits to Github, everything was fine, but once I did Github signals some vulnerabilities and after fixing them npm run dev doesn't work anymore.

tried multiples solutions but nothing worked, reinstalled suspicious modules, reinstalled node modules after running npm cache clean --force

This is the error I got 

   npm run dev

"webpack": "^4.43.0",

"webpack-bundle-analyzer": "^3.3.2",

"webpack-cli": "^3.3.11",

"webpack-dev-server": "^3.1.11",

I hope I provided everything for you guys, if not I will immediately provide anything to help clarify my problem, as I said I'm a newbie to web development.

UPDATE: I've trying to figure out the reason behind such error, the problem occurs after updating webpack-dev-server Version that works :

"webpack-dev-server": "^2.9.1"

Version with errors :

"webpack-dev-server": "^3.11.0"

Is it okay if I ignore vulnerabilities found? Because trying to fix them causes this error.

Thanks

This is not an issue with webpack or webpack-dev-server itself, but with the copy-webpack-plugin plugin.

With the update to the 6.x major version came a breaking change: instead of just passing the array with the config patterns directly to the CopyWebpackPlugin constructor, your now have to wrap it in the patterns property of an object and pass that.

Old syntax:

    new CopyWebpackPlugin(
      [
        { from: 'src/xxx.ext', to: 'dist/xxx.ext' },
        { from: 'src/yyy.ext', to: 'dist/yyy.ext' }
      ]
    )

New syntax:

    new CopyWebpackPlugin(
      { 
        patterns: [
          { from: 'src/xxx.ext', to: 'dist/xxx.ext' },
          { from: 'src/yyy.ext', to: 'dist/yyy.ext' }
        ]
      }
    )

They did that because the constructor now supports an additional options property: https://webpack.js.org/plugins/copy-webpack-plugin/#options-1
