Read In App Purchase issue

Hello I wanted to ask some questions about the “Read In-App Purchase” node I can’t make it work despite I have configured things correctly as written in the EU4 documentation.

  • On UE4 I configured the nodes as follows, within the widget to buy the premium currency of my game, the following event is called inside the “Event Construct”.

  • Within the google play console I have configured the packages that you can buy in this way

Why when I try to do the “development build” the node to read the “In App Purchase” always goes to “On Failure”?

I’ve already added the Game App ID and some extra permissions. What i’m doing wrong ?

Can someone help me? Because I can’t find a lot of information around.
