Electron MacOS app 'Not Available for Testing' in Testflight

Question

I'm working on a universal MacOS app in Electron, and while I've gotten pretty far, I can't seem to figure out how to enable it for testing in Testflight.

I keep running into the following error in App Store Connect no matter what I do:

I'm using:

• electron-builder: 23.0.8
• electron: 17.4.3
• electron-builder-notarize: 1.4.0

I'm building on an M1 Macbook Air, Monterey 12.3.1.

Varying useful stuff I've found:

• https://github.com/electron/osx-sign/issues/251
• https://developer.apple.com/forums/thread/689377

Answer 1

After looking through all these, and just playing around with adding different entitlements, it was resolved with the following settings. I honestly have no idea which of these is relevant at this point, and after days of debugging I am beyond the point of caring haha. But for future internet travelers who find themselves stuck, here is what I have that got me through:

package.json relevant section (added loginhelper!)

"build": {
    "appId": "com.xxxxxx.xxxxxx",
    "afterSign": "electron-builder-notarize",
    "mac": {
        "category": "public.app-category.entertainment",
        "darkModeSupport": true,
        "hardenedRuntime": true,
        "gatekeeperAssess": false,
        "entitlements": "build/entitlements.mac.plist",
        "entitlementsInherit": "build/entitlements.mac.plist",
        "icon": "build/icon.icns",
        "target": [
            {
                "target": "mas",
                "arch": "universal"
            },
            "dmg"
        ]
    },
    "mas": {
        "type": "distribution",
        "hardenedRuntime": false,
        "provisioningProfile": "embedded.provisionprofile",
        "entitlements": "build/entitlements.mas.plist",
        "entitlementsInherit": "build/entitlements.mas.inherit.plist",
        "entitlementsLoginHelper": "build/entitlements.mas.loginhelper.plist"
    }
}
