Cannot find .proto files using electron forge webpack template

[SitraLuka]

My project is using Electron Forge's create-electron-app package with the webpack template.
When I try to run my application I get the following error:

PUSH_RECEIVER:::Error while starting the service [Error: ENOENT: no such file or directory, open '[...]\.webpack\main\checkin.proto'] {
  errno: -4058,
  code: 'ENOENT',
  syscall: 'open',
  path: '[...]\\.webpack\\main\\checkin.proto'
}

Note that I'm using pnpm as my package manager. I know that sometimes gives some issues when a package is trying to execute post-build scripts but I don't think that's the issue here.

I kept the webpack config pretty standard. Not sure if I'm supposed to add anything to it in order to copy the proto files.

I've managed to fix the issue by adding the following to webpack.plugins.ts:

new CopyPlugin({
  patterns: [
    { from: '*.proto', context: 'node_modules/firebase-electron/dist/' },
    { from: 'utils/*.proto', context: 'node_modules/firebase-electron/dist/' },
  ],
}),

I'm not sure if this is the right approach but it does work.
