Read.SAPModel Error

I have been working with the DynamoSap package and the example scripts put together by Core Studio to use Dynamo to import my structure from SAP to Revit. I am using the newest version of the package (1.2.10), as well as SAP 2000 v19. I tested the script with sample SAP files as well as a simple one I created and dynamo was able to read each file.

However, when I try to read my larger project file I am getting an error message the Parameter name: Argument ‘Array’ is nothing.


Does anyone have any ideas on what would be different between the SAP files causing this “Parameter name: Argument ‘Array’ is Nothing.” error to occur on one of them? Is there a setting or parameter in SAP I need to adjust?
