I am trying to set color of a border color, but when I do it and try to access it, it throws an exception
"An unhandled exception of type ‘System.NullReferenceException’ occurred in Aspose.Cells.dll
Aditional information: Object reference not set to an instance of an object"
Attached you can find a screenshot of the problem, and also a reproducer.
Please let me know if I am doing something wrong or if there is a bug in Aspose.Cell library.
