Thanks for report this error in sample, I will update it for API help. Please replace the line using below line on your side:

Print #1, "      Category: " & material.CategoryName

The problem is because some material asset's category is empty.



If this solves the problem please click ACCEPT SOLUTION so other people can find it easily.
