Unable to fetch offerings from playstore

I am trying to use RevenueCat for my flutter application. Now app is work fine in the IOS but in the android it gives ConfigurationError. Below is the debug log.

I followed the guidelines of revenuecat when adding products to the playstore. But they are not working. and also I need to say that the currently app is not in review and we are trying with a another version of the same app that is in the internal testing.
