Error while archiving react-native iOS project for testflight, app-icon

I am trying to Archive a react-native iOS app in preparation of distributing via TestFlight. I already added app icons of several resolutions, but I am still getting errors of missing app icons.

and here is the error.

I also have App Icons Source set to AppIcon in the General tab of the project.

This is a react native app, which I am trying to distribute it to testers via TestFlight.
