In this paper, it said that it give a method to deal with hanging node using

Xuhong,
the error message tells you the story: The element you are trying to use
apparently does not implement hanging node constraints. Since you don't show
the code, I can only assume that you use the FENedelecSZ element, which indeed
does not implement these constraints.
The paper suggests that it does, but I don't think that the implementation of
these constraints have ever been submitted as a patch to deal.II. It would
probably be useful for you to ask the authors about the status of the changes
they must have made.
Best
