Ah, actually it's default to untitled but if not, it should given. Let me change it.
not sure if this will be useful to you but after the journey i went on to find them i wanted to share them with someone. here are the Bundle IDs for some MacOS non beta versions
com.apple.InstallAssistant.Catalina
com.apple.InstallAssistant.macOSVentura
com.apple.InstallAssistant.macOSBigSur
com.apple.InstallAssistant.macOSMonterey
i was able to find these based on what i read here https://pspdfkit.com/guides/ios/faq/finding-the-app-bundle-id/
On any recent new macOS, likely using softwareupdate command would be better solution to download installer. For example,
$ softwareupdate --list-full-installers
$ softwareupdate --fetch-full-installer --full-installer-version 14.0

It was necessary to add the option
-volname $DISK_IMAGE_NAMEtohdiutil createwhen using under conditions where the volume does not exist.
