Error occur when I input data through pywwt #154

When I try to pass a 322322 rows table to WWT windows client through layer.update in pywwt, I got this error in visual studio 2017 debug mode

Error: System.ArgumentOutOfRangeException: ?????????????? DateTime? ???: t ? System.DateTime.op_Subtraction(DateTime d, TimeSpan t) ? TerraViewer.SpreadSheetLayer.PurgeByTime() ? TerraViewer.SpreadSheetLayer.LoadFromString(String data, Boolean isUpdate, Boolean purgeOld, Boolean purgeAll, Boolean hasHeader) ? TerraViewer.SpreadSheetLayer.UpadteData(Object data, Boolean purgeOld, Boolean purgeAll, Boolean hasHeader) ? TerraViewer.LayerManager.UpdateLayer(Guid layerID, Object data, Boolean show, String name, Boolean noPurge, Boolean purgeAll, Boolean hasHeader) ? TerraViewer.HTTPLayerApi.Proc

And the python.exe terminal show this messae:

D:\Tools\Visual Studio 2017\Shared\Python36_64\lib\site-packages\pywwt\windows\misc.py:24: UserWarning: No parser was explicitly specified, so I'm using the best available HTML parser for this system ("lxml"). This usually isn't a problem, but if you run this code on another system, or in a different virtual environment, it may use a different parser and behave differently.

The code that caused this warning is on line 24 of the file D:\Tools\Visual Studio 2017\Shared\Python36_64\lib\site-packages\pywwt\windows\misc.py. 
To get rid of this warning, pass the additional argument 'features="lxml"' to the BeautifulSoup constructor.
  soup2 = BeautifulSoup(resp_str)

I try to google the first error. It seems that's from WWT windows client.

the data snapshot is here: image

WWT version is 6.0.11.1 OS: windows 10

After I modified the file base on notice from error 2, it still happens. Finally, I avoid it by output a csv file then use wwt.load.

Thanks in advance for any replies.

Is the build debug or release? In debug it might be targeting Win32 and have a 4gb address limit. There may be a max string size and the error is cause trying to parse the last line cut in half.

Could I try to repro this and see what the failure is?

Thanks for your reply.

what's the meaning of

Is the build debug or release?

I debug my code in visual studio 2017 debug mode. Windows client is installed from official site exe program.

Because my output file is nearly 300MB, I think you can download the raw data here

http://www.astroblend.com/data/sphdec.tar.gz

and then merge middle 3 columns in first 25 .txt files . the layer is created by wwt.ney_layer().

layer's frame = Sandbox CoordinatesType in property_dict is Rectangular

Then pass the data to wwt layer use layer.update. The error1 may occur. The error1 may need to use some IDE to reproduce. Feel free to tell me if it can't be reproduced, I can send my file to you through email or other ways.
