Dear macOS Productbuild and pkgbuild experts (without/not using the Xcode)

This is my last hurdle after going through a huge learning journey on product build and pkgbuild

I get the error from Appstore

* "ITMS-90264: The lowest minimum system version [none] in the Product
Definition Property List must equal the 'LSMinimumSystemVersion'
value [10.9] in the 'Info.plist'. "

In my App/Contents/Info.Plist there is

```
`<key>LSMinimumSystemVersion</key>
  <string>10.9</string>`

```

Now when I build the package as per the following sequence

```
 `pkgbuild --analyze --root "./pkgbuild/app_path/" app.plist

    pkgbuild --root "${ROOTFOLDER}" --identifier "${IDENTIFIER}" --version ${VERSION} --    component-plist ./app.plist  --install-location "/Applications" \
     --sign "${IDENTITY}" \
     "${PKGNAME}.pkg"

    #productbuild --synthesize --package Final.pkg distribution.xml

    productbuild --distribution ./distribution.xml --resources ~/Desktop/resources --identifier com.myorg.uniqueid --version ${VERSION} --sign "${IDENTITY}" --product ~/Desktop/modInfo.plist outputFinal.pkg`

```

Question Where do I incorporate the the lowest minimum system version none in the Product Definition Property List " to 10.9 ? and what do I need to insert in what file, how?

Deeply appreciate if I can get some pointers.

Thanks in advance
