question

Here's the code from Unity

public void UnlockContainer(string containerId,
                            Action<List<InventoryItem>> success,
                            Action<string> error)
{
    var request = new UnlockContainerItemRequest();
    request.CatalogVersion = "Rhino Store";
    request.ContainerItemId = containerId;
    Action<UnlockContainerItemResult> callback;
    callback = r =>
    {
        var items = r.GrantedItems
                     .Select(i => CloudDataFactory.GetInventoryItem(i));
        if (success != null) success(items.ToList());
    };
    Action<PlayFabError> errorCB = e =>
    {
        if (error != null) error(e.GetFormattedError());
    };
    PlayFabClientAPI.UnlockContainerItem(request, callback, errorCB);
}

Everything else seems fine. Any help will be appreciated.
