webpack: configuration.entry error (passing an Array of paths)

I’m submitting a bug report

passing an Array of paths causes a webpack validation error

Webpack version: 2.1.0-beta.25

Please tell us about your environment: macOS Sierra

Current behavior:

passing an Array of paths outputs a WebpackOptionsValidationError


  entry: [
    'webpack/hot/dev-server',
    `webpack-dev-server/client?http://127.0.0.1:${port}`,
    './src/js/script.js',
    './src/css/style.css',
    './src/index.html'
  ],

configuration.entry should be one of these:
   object { <key>: string | [string] } | string | [string]

Expected/desired behavior:

passing an Array of strings should work? ([string])

@jlabaj Alright, the issue is reproducible with your repo (for me). As @duivvv and @EvNaverniouk pointed out, the problem seems this string 'webpack/hot/dev-server'. If you remove it from the list this issue does not occur.

So I thought, maybe webpack tries to add 'webpack/hot/dev-server' to the entry points again because you specified --hot (as described in Docs and this GitHub-Issue) and this causes some broken config array. But even without this parameter the same error message occurs.

Maybe @gajus can help us?

I get duplicate entries in the array. And so, webpack-dev-server is failing.

"data": [
          "/Users/vijayst/Documents/react/sam/samwise/node_modules/webpack-dev-server/client/index.js?http://localhost:8080",
          "webpack/hot/dev-server",
          "react-hot-loader/patch",
          "webpack-dev-server/client?http://127.0.0.1:8080",
          "webpack/hot/dev-server",
          "./src/app"
        ]

Hi,

I’m having this issue with múltiple entry points and without dev server, in a production build.

With just one entry points It works fine.
