Electron forge webpack remove renderer config

Question

I use Electron Forge with the webpack template. For the renderer i use an url (mainWindow.loadURL(startURL);) and want to remove everything in the webpack config that has to do with the renderer. Is there a way to use the webpack template without the webpack creating the "renderer" part

package.json

"config": {
    "forge": {
      "packagerConfig": {},
      "makers": [
        {
          "name": "@electron-forge/maker-squirrel",
          "config": {
            "name": "webpack_test"
          }
        },
        {
          "name": "@electron-forge/maker-zip",
          "platforms": [
            "darwin"
          ]
        },
        {
          "name": "@electron-forge/maker-deb",
          "config": {}
        },
        {
          "name": "@electron-forge/maker-rpm",
          "config": {}
        }
      ],
      "plugins": [
        [
          "@electron-forge/plugin-webpack",
          {
            "mainConfig": "./webpack.main.config.js",
            "renderer": {                                        <<<< I want to remove this part
              "config": "./webpack.renderer.config.js",
              "entryPoints": [
                {
                  "html": "./src/index.html",
                  "js": "./src/renderer.js",
                  "name": "main_window"
                }
              ]
            }
          }
        ]
      ]
    }
  },

If I simply remove the part I get the message that no entryPoint is defined.

An unhandled error has occurred inside Forge:
