Schwab-NullReferenceException

I am getting a NullReferenceException using the Schwab adapter and pulling up a chart. Here's a portion of the log:

Here is the latest exception detail:

CODE:
10/18/2024 08:11:42:613
Schwab
Error getting History (MARA): Object reference not set to an instance of an object.
NullReferenceException
Object reference not set to an instance of an object.
   at WealthLab.Schwab.SchwabHistorical.RequestHistory(String symbol, HistoryScale scale, DateTime startDate, DateTime endDate, Int32 maxBars, Boolean includePartialBar, Boolean corrections, Nullable`1 lastRequestDate)
   at WealthLab.Schwab.SchwabHistorical.GetHistoryInternalWithCorrections(String symbol, HistoryScale scale, DateTime startDate, DateTime endDate, Int32 maxBars, DateTime lastRequestDate)
   at WealthLab.Data.DataProviderBase.GetHistory(String symbol, HistoryScale scale, DateTime startDate, DateTime endDate, Int32 maxBars, DataRequestOptions cb)
   at WealthLab.Data.HistoricalDataValet.FindRepository(String v, HistoryScale map, DateTime serv, DateTime last2, Int32 res3start, IHistoryProvider cfg4, DataRequestOptions info5)

So, the exception occurs, but then it reconnects and the data is fetched. But, if you change the symbol, the error occurs again and then the data is fetched. Lather, rinse, repeat.

I'm not sure, but it seems I had streaming active on a chart yesterday. I disconnected the streaming. I put the computer to sleep. Today, I pulled up a new chart and the errors started. I can close all charts and bring up a new one and the problem persists.

If you need more info, please let me know.
