Getting error when trying to fetch ProductDetails from Google Play store in Flutter - repost

Hi all, reposting here because, I got no reply in Dashboard & Tools.

This is the error I am getting: 

W/[Purchases] - WARN(24005): There is a problem with your configuration in Play Store Developer Console. More info here: https://errors.rev.cat/configuring-products

I am following the guide here: 

• Why are offerings or products empty?

• Why are offerings or products empty?

Have not had the app published yet. But the interesting thing is in RevenueCat Dashboard, I can IMPORT my iNAPP products. RevenueCat can identify a new product created in my Play console, import it without any issues but can’t fetch ProductDetails! Is this normal?

Again, have not published my app in Closed testing yet, waiting for review to finish. But since I’m a license tester on a physical phone, and RevenueCat can fetch the products themselves from the Dashboard, maybe there is something else I am missing?
