In ios, the crash occurred when consumeProduct method is called.

Unhandled Exception: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

For IOS
When OnPurchaseSucceeded of OpenIABEventManager is called, have to change storeSKU to GameSKU.

So changed as follows :

OpenIABEventManager.cs

#if UNITY_IOS
    ...
    ...
    private void OnPurchaseSucceeded(string json)
    {
        if (purchaseSucceededEvent != null)
        {
            //purchaseSucceededEvent(new Purchase(json)); // <-- have to change storeSKU to gameSKU.
            purchaseSucceededEvent(new Purchase(new OnePF.JSON(json)));
        }
    }
    ...
    ...
#endif

Good luck!!!
