electron-webpack issue on --env.production parameter

[channelaffairs]

• Version:
  @expo/electron-adapter": "0.0.55"
  electron: "13.1.2"
  electron-builder: "22.11.7"

No electron-updater used

• Target:
  Mac, Win and Linux (same issue)

When attempting to build for Mac/Win/Linux , the electron-webpack somehow does not handle the absence of the --env.production parameter that from my scripts is not even explicitly declared

Commenting the lines in the screenshot solves the problem and allows me to build on all platforms Below the command that I execute to start the build

build-electron: yarn build-deps && yarn electron-webpack && yarn electron-builder -mwl --dir -c.compression=store -c.mac.identity=null
The command above follows (as far as I'm aware) the guidelines provided by expo for the correct integration with electron

Thanks Guys!

The issue was coming from weback 4.x.x being not compatible with electron-webpack at present time...
I wish this stuff was documented guys as I'm sure the more devs will adopt web pack 4 the more this issue will occur

Anyhow for future reference use the following versions of webpack and webpack-cli:

webpack-cli: 3.3.10 webpack: 3.12.0
