Electron Forge version

Electron version

v31.3.1

Operating system

macOS 14.6.1

Last known working Electron Forge version

No response

Expected behavior

afterPrune should be executed when running npx electron-forge package --arch=arm64 --platform=linux ./electron

Actual behavior

the hook is only executed with DEBUG=electron-packager npx electron-forge package --arch=arm64 --platform=linux ./electron

Steps to reproduce

I have a react app in the main folder project and electron files into ./electron.

This is the forge.config.js file:

const { FusesPlugin } = require("@electron-forge/plugin-fuses")
const { FuseV1Options, FuseVersion } = require("@electron/fuses")


module.exports = {
    packagerConfig: {
        prune: true,
        afterPrune: [
            async (buildPath, electronVersion, platform, arch) => {
                throw new Error("This is a test error")
            },
        ],
    },
    rebuildConfig:{},
    makers: [
        {
            name: "@electron-forge/maker-zip",
            platforms: ["linux", "darwin"],
        },
    ],
    plugins: [
        new FusesPlugin({
            version: FuseVersion.V1,
            [FuseV1Options.RunAsNode]: false,
            [FuseV1Options.EnableCookieEncryption]: true,
            [FuseV1Options.EnableNodeOptionsEnvironmentVariable]: false,
            [FuseV1Options.EnableNodeCliInspectArguments]: false,
            [FuseV1Options.EnableEmbeddedAsarIntegrityValidation]: true,
            [FuseV1Options.OnlyLoadAppFromAsar]: true,
        }),
    ],
}

the error is not thrown unless you use DEBUG=electron-packager
