Error message parameter "masking" cannot be added to the family

i m trying to copy sheet from one project to another project (blank project) using pyrevit, there is an error message “parameter “masking” cannot be added to the family”. I m using revit 2023. What is this error and how do i get over it? I put this in perplexity, and i got the following answer.

This error usually means that, while copying the sheet, some element on that sheet has a shared or project parameter called “Masking” that Revit 2023 is refusing to bind into at least one of the families involved.

i checked both project parameter under Manage, there is no such parameter. Has anyone encountered this error before and how do you get over it?
