Getting 'storekit_duplicate_product_object' error trying to buy a non-consumable. (iOS)

[Jeff Jorczak]

Somehow while testing an app I got into a loop where I get this error every time I try to buy a product:

    final PurchaseParam purchaseParam = PurchaseParam(
        productDetails: product,
        applicationUserName: null,
        sandboxTesting: kUseStoreSandbox);

    _inAppPurchaseConnection.buyNonConsumable(purchaseParam: purchaseParam);

The purchase collection comes back empty, so the purchase I made in a previous iteration of testing must be in a state of pending. It appears I have no way to retrieve it to cancel or complete it. Anyone else worked through similar?

I believe this is happening because my listener is not getting called to "unpend' the purchased transaction. Posting as another topic.
