Android IAP's not working on Android. NullPointerException on GPBilling_PurchaseProduct

After examining this YoYoGames page about IAP's on Android I implemented the default code from the GooglePlayServices package from the marketplace.

When calling the function GPBilling_PurchaseProduct() in the Left Mouse Press Event I get this error:

Does anyone else have this error?

I have:

Set up a store presence for the game, uploaded an APK
Set up IAPs for the game on the store app console
Add the required extension to GameMaker Studio 2

Did you ever find a solution for this? I am getting the same error on the latest GPB extension when i call ` GPBilling_PurchaseProduct`. This is on a game that is years old and has had working IAP's. Just trying to update to the new GPB code. I know the IAP is working because `GPBilling_QueryPurchasesAsync` is correctly getting the already purchased item.
