Bundle is invalid when submitting to App Store Connect

I am attempting to submit my first MacOS application to the App Store Connect. I have gone through all the steps in the documentation and used Packages to create my PKG flat file. Here are the issues:
Validation failed (409). This bundle is invalid. Scripts archive is present but unused (no script references in PackageInfo).
I have found no reference to a scripts archive anywhere in the info.plist or other files within the package. I’d sure appreciate any recommendations where to look to resolve this error!

Thanks in advance.
