GraphQL requires you to know upfront what you want to receive. You can't for example receive data for a menu with submenus with undetermined level of depth. You can hack your way around the problem, but it's ugly.
Another problem GraphQL hasn't tackled (afaik) is polymorphism. You can say "hey give me this person" or "give me this company", but what if you want a customer that can be either a person or a company?
