You seem to have some null values in your points list.
Avoid feeding a list with null values into Topography.ByPoints
You could do one or both of the following …

• Flatten/Clean the Points list before connecting to Topography.ByPoints
• Ensure that X,Y and Z have the same number of valid numeric values in the excel sheet

Success!!Thank you Vikram
