Failed to read the 'localStorage'

Describe the bug Everything works just fine in development mode but I’m getting this error in the devtools console after building my app: Uncaught DOMException: Failed to read the ‘localStorage’ property from ‘Window’: Access is denied for this document. at app://./js/chunk-vendors.0b3afa94.js:175:17895 at Object.b25c (app://./js/chunk-vendors.0b3afa94.js:175:18055) at l (app://./js/app.a7acfa50.js:1:618) at Module.56d7 (app://./js/app.a7acfa50.js:1:7568) at l (app://./js/app.a7acfa50.js:1:618) at Object.0 (app://./js/app.a7acfa50.js:1:3170) at l (app://./js/app.a7acfa50.js:1:618) at n (app://./js/app.a7acfa50.js:1:388) at app://./js/app.a7acfa50.js:1:3135 at app://./js/app.a7acfa50.js:1:3140

To Reproduce npm run electron:build and then open the the app

Expected behavior Get access to LocalStorage

Environment (please complete the following information):

• OS and version: Linux Ubuntu Studio 18.10
• node version: 12.1.0
• npm version: 6.9
• yarn version (if used): 1.10.1
• vue-cli-plugin-electron-builder version : 1.3.1
• electron version: 5.0.0
• other vue plugins used: vue-router, vuex, vuex-persistedstate, heap/electron-cookies (is not a vue plugin but could relate with the issue), vuetify, cli-babel and eslint. Theres also electron-rebuild (the only way I could find to correctly complite the native dependency “serialport”)
• custom config for vcp-electron-builder:

module.exports = {
  pluginOptions: {
    electronBuilder: {
      // List native deps here if they don't work
      externals: ['serialport', 'osc'],
      nodeModulesPath: ['./node_modules']
    }
  }
}

• (if possible) link to your repo: https://github.com/gilfuser/deslugarejo/tree/backendless

Additional context This only started after I changed to electron 5.0.0 and node 12.0.0. Later, to correct another problem, namely an “error 138” while trying to build the app I updated it to 12.1.0.

Thank you for this project. Since now I’m having a solid experience with it.

best regards, Gil

background.js use standard: true,

protocol.registerSchemesAsPrivileged([
  { scheme: 'app', privileges: { standard: true, supportFetchAPI: true, secure: true } }
])

registerSchemesAsPrivileged was no help … in my case, i had to run electron-builder
