BalanceTransactionService.ListAutoPaging Null Reference Exception

[davetheunissen]

When using the ListAutoPaging feature for BalanceTransactions, the service throws a null reference exception as it tries to go past the number of records in the result set.

i.e. the default option is to limit the returned result set to 10 records.
if I run the following, 10 records will be added to my list and the loop will throw the exception when trying to access an 11th record.

foreach (var balanceTransaction in _balanceTransactionService.ListAutoPaging())
{
      balanceTransactions.Add(balanceTransaction);
}

OSVersion: Windows 10 : Build 17134
.NETVersion : dotnet core 2.1
StripeVersion: 27.16.0

Hi @davetheunissen. Can you share the full stacktrace for the exception?

Here you go... We are getting the same exception for charges as well.

Thanks! I think I know what the bug is. I'll update here once I confirm or if I need more information.

Actually, can you try the following? It will help me confirm if the issue is what I think it is:

var options = new BalanceTransactionListOptions();
foreach (var balanceTransaction in _balanceTransactionService.ListAutoPaging(options))
{
      balanceTransactions.Add(balanceTransaction);
}

Hi @ob-stripe, confirmed the issue is caused by a null options object even though the LastAutoPaging method has a default parameter for the options that accept nulls.

Thanks @davetheunissen! We will release a fix soon.

We just released version 27.16.1 which should fix the issue. Thanks for the report, and sorry for the inconvenience!
