From Documentation

....

To enable data sharing, use Xcode or the Developer portal to enable app groups for the containing app and its contained app extensions. Next, register the app group in the portal and specify the app group to use in the containing app. To learn about working with app groups, see Adding an App to an App Group. ....

I think in your case, this is not set up properly?
