What does the error "object '' not found" mean in the context of the ggraph function throwing an eval_tidy error with centrality as an argument?

edit

The error "object not found" in the context of the ggraph function throwing an eval_tidy error with centrality as an argument typically means that the object specified within the function's argument, i.e. centrality, cannot be found in the environment or has not been properly defined. This could be due to a misspelling of the object's name or not loading the necessary library to create the centrality measure.
