Bimorph Sheet.Duplicate Error

I am using the Bimorph node Sheet.Duplicate. I have used this successfully recently. Lately when I run it I get the following error:

“Warning: Sequence contains no elements
Internal error, please report: Dereferencing a non-pointer.
Internal error, please report: Dereferencing a non-pointer.”

I have not received this error before. I have uninstalled the Bimorph nodes and reinstalled, as well as rebuilt the script. Any help is appreciated.

Thanks in advance.

@steven.richter I get this warning when my sheet is absolutely blank (no views or titleblock)

This might be because of your sheet list containing some null values.
Try using the List.Clean node and see if it helps

In case if that doesn’t work, @Thomas_Mahon might be able to help you out here.
