Sandbox entitlements error ITMS-90296

I am having problems submitting my app to the app store. Where I am running into an error is sandbox not being enabled. I am adding entitlements when I sign the app, but apparently it is not working. This is the error that is coming up.

ERROR ITMS-90296: "App sandbox not enabled. The following executables must include the "com.apple.security.app-sandbox" entitlement with a Boolean value of true in the entitlements property list: [( "com.site.app.pkg/Payload/App.app/Contents/Frameworks/App Helper EH.app/Contents/MacOS/QuizzUmmah Helper EH", "com.site.app.pkg/Payload/App.app/Contents/Frameworks/App Helper NP.app/Contents/MacOS/App Helper NP", "com.site.app.pkg/Payload/App.app/Contents/Frameworks/App Helper.app/Contents/MacOS/App Helper", "com.site.app.pkg/Payload/App.app/Contents/MacOS/App" )] Refer to App Sandbox page at https://developer.apple.com/devcenter/mac/app-sandbox/ for more information on sandboxing your app."

Here are my 2 entitlements: Parent:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>com.apple.security.app-sandbox</key>
    <true/>
    <key>com.apple.security.application-groups</key>
    <string>'My team id'.com.site.app</string>
  </dict>
</plist>

child:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

    <key>com.apple.security.app-sandbox</key>
    <true/>
    <key>com.apple.security.inherit</key>
    <true/>
  </dict>
</plist>

And my build script:

 electron-packager . App --identity='3rd Party Mac Developer Application: 'Company' ('My team Id')' --sign-entitlements='./entitlements.mas' --sign-entitlements-inherit='./inherit.entitlements.mas' --osx-sign --app-version='1.0.0' --build-version='1.0.100' --platform=mas --app-bundle-id='com.site.app' --helper-bundle-id='com.site.app.helper' app-category-type=public.app-category.games --arch=all --icon=icon.icns --overwrite --asar",
