Pre-flight checklist

• I have read the contribution documentation for this project.

• I have searched the issue tracker for a bug that matches the one I want to file, without success.

Electron Forge version

7.6.0

Electron version

30.0.1

Operating system

Win 10 22H2

Last known working Electron Forge version

No response

Expected behavior

ignore logic

ignore(path) {
    if (path === '/app') return false;
    if (path === '/dist') return false;
    if (path === '/dist-client') return false;
    if (path === "/package.json") return false;
    return true
}

should output

.
└── Project ROOT/
    ├── app/
    ├── dist/
    ├── dist-client/
    └── package.json

Actual behavior

Got some error or not functioning.

Steps to reproduce

I have the project file like this

.
└── Project ROOT/
    ├── src/
    ├── .angular/
    ├── app/
    ├── node_modules/
    ├── projects/
    │   └── client/
    ├── dist/
    ├── dist-client/
    ├── angular.json
    ├── package.json
    └── ....

What I want to package is only 3 folders, dist, dist-client, app and package.json, the final output like this:

.
└── Project ROOT/
    ├── app/
    ├── dist/
    ├── dist-client/
    └── package.json

so I try to ignore files

ignore(path) {
    if(!path) return false;
    if (path === '/app') return false;
    if (path === '/dist') return false;
    if (path === '/dist-client') return false;
    if (path === '/package.json') return false;
    return true
}

When running this got error.

An unhandled rejection has occurred inside Forge:
Error: The main entry point to your app was not found. Make sure "C:\Projects\app\main.js" exists and does not get ignored by your ignore option
at validateElectronApp (C:\Projects\node_modules\@electron\packager\dist\common.js:104:15)
    at async WindowsApp.buildApp (C:\Projects\node_modules\@electron\packager\dist\platform.js:126:9)
    at async WindowsApp.initialize (C:\Projects\node_modules\@electron\packager\dist\platform.js:120:13)

    at async Promise.all (index 0)
    at async packager (C:\Projects\node_modules\@electron\packager\dist\packager.js:237:22)

Then I remove if(!path) return false;

ignore(path) {
    // if(!path) return false;
    if (path === '/app') return false;
    if (path === '/dist') return false;
    if (path === '/dist-client') return false;
    if (path === '/package.json') return false;
    return true
}

It no errors, but seems package.json has been ignored, so the Preparing native dependencies is not running.

✔ Checking your system
✔ Preparing to package application
✔ Running packaging hooks
  ✔ Running generateAssets hook
  ✔ Running prePackage hook
❯ Packaging application
  › Determining targets...
  ❯ Packaging for x64 on win32
    ✔ Copying files
    ⠹ Preparing native dependencies
    ⠹ Finalizing package
◼ Running postPackage hook

but I try the other way, like this:

ignore(path) {
    if (path === "/src") return true;
    if (path === "/angular.json") return true;
    if (path === "/node_modules") return true;
    if (path === "/.angular") return true;
    if (path === "/projects") return true;
    ..... and some other folder and files
    return false
}

That the output is what I expected

.
└── Project ROOT/
    ├── app/
    ├── dist/
    ├── dist-client/
    └── package.json
