node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^

[Error: Unable to spawn executable at '/private/var/containers/Bundle/Application/AAD2D010-58DC-4E8C-9057-865D30392D5D/Snapchat.app/PlugIns/SnapchatLocationPushExtension.appex/SnapchatLocationPushExtension': Undefined error: 0]

also, while i'm here, could you add an option to not package the dumped app into an ipa? my script relies on bagbak dumping into a folder, so i'd appreciate it :)

@asdfzxcvbn Snapchat has a malformed package.

Workaround: SSH to device, chmod +Xx /private/var/containers/Bundle/Application/AAD2D010-58DC-4E8C-9057-865D30392D5D/Snapchat.app/PlugIns/SnapchatLocationPushExtension.appex/SnapchatLocationPushExtension
