The problem is going to be with your data types.
I’m guessing your instance field is coming in as a string - not a bool. You can see Excel is importing as strings. You’ll need to convert those to bools.
The error message suggests it is the type that is bad as well. This is a string, but I’m guessing there is a typo or invalid category in the list.
I’m not sure this is best practice, as this routine can create different shared parameters - even though it is reading the same Excel spreadsheet - in different projects. It is the GUID that matters. The Parameter.CreateSharedParameter node has to make a GUID on the fly to build the shared parameter and then imports the parameter. All ok, until you want to share information between projects or use the parameter inside a family.
This will really fail if you try and use it when you are building families. Each time you start building a new family - you get a unique parameter. So you build Door A with “My Parameter” and then Door B with “My Parameter” - you get two completely unique parameters.
But that isn’t an issue with this node - as it only runs on a project. It should really be called CreateProjectSharedParameter.
And if you are trying to call it on a family file - it will give you the exact error you have posted.
