I exported the feature definitions from the new OpenRoads CE version 2 file titled "Survey_Features_Annotations_Levels_Elem Temp Imperial.dgnlib to preform some bulk editing but when I tried to convert it to an xlsx format using the features_importexport_excel.exe tool I receive an error message that reads "Error exporting features to Excel: Object reference not set to instance of an object.".
What does this error message mean and how can I move past it?
