When i run one of dynamo script , It is come with Warning. “Warning: Internal error, please report: Dereferencing a non-pointer.”
This is caused by “GetStructureByName” node’s results are null values.
I don’t know how the naming of the structures is, in the document you are working, to me it seems like the document you are working on has structure names that are not equal to the Excel file. Firstly I would check that out on Revit, I guess you have already checked that out earlier since it is the first thing that comes to mind.
I don’t know if this works but I’d like to give a suggestion.

in this post, GetStructureByName node is working and the results seem in different formats: such as “Structure(Name=xxxx)”. It isn’t shown in the post, how the names are pulled to the node. Maybe data should be in a specific format. If I were you, I would copy and save another Excel file and work on changing the format to this format “Structure(Name=xxxx)”. Maybe it would work. Sorry if that suggestion takes your time without giving any solution, I am also a beginner.
Of Course, I don’t know why.
Need to resolve
Start by selecting a structure, and seeing what it reports it’s name as. If that isn’t exactly in the list of excel data the by name won’t work.
