Build not working for multiple browser windows

I seem to have the same problem as in: #102

Describe the bug When creating an application with more than one window, the build fails with message: Building modern bundle for production...(node:67207) UnhandledPromiseRejectionWarning: Error: ENOENT: no such file or directory, open '/Users/.../dist_electron/bundled/legacy-assets-index.html.json'

To Reproduce Clone https://github.com/utoppo/vue-cli-plugin-electron-builder-build-problem Try to build with: yarn electron:build

Expected behavior Build/Bundling Process should finish without error.

Environment:

• OS and version: OSX 10.12.6
• node version: v11.0.0
• npm version: 6.4.1
• yarn version : 1.9.4
• vue-cli-plugin-electron-builder version : 1.0.0-rc.10
• electron version: 4.0.0
• custom config for vcp-electron-builder:

I fixed the missing legacy-assets-page.html.json bug with 1.1.1, and created a multipage demo app. Let me know if that works for you or if you have more questions.

It doesn’t work in our case! You should replace fileName to filename ! Changing name of option in vue.config.js does not help.

See: https://github.com/nklayman/vue-cli-plugin-electron-builder/commit/bafd557d8b11c2f6de3b600b2cd2fcbc4a6de351#r32880694

Otherwise we get errors and build never finishes:
