When importing from Excel, the User Action Required window reports something similar to:

An exception occurred while generating a file from Catalogue XML
Value cannot be null.

Parameter name: Argument 'Array' is Nothing.
System.ArgumentNullException: Value cannot be null.
Parameter name: Argument 'Array' is Nothing.

The Excel file contains a reference to a shape that does not exist on the stencil being used to generate the new maps. As a consequence, a generic "Unknown Shape" is used and this causes the error.
The error can be avoided by ensuring the stencil contains all the shapes that are referenced in the Excel file. The error reporting was resolved on Process Navigator 4.62
Applies to:
  • Process Navigator 4.60, 4.61
