What do you dislike about GraphQL?

Hey everyone!

I‘m currently working on my own backend framework for nodejs. It‘s basically a very fancy GraphQL server.

So, I was wondering what backend devs like least about working with Apollo Server and/or similar frameworks, so I can design my framework to address those issues.

Please tell me in the comments! Also, your problem doesn‘t have to be a problem with common server frameworks; I‘d be just as happy to hear your general problems with GraphQL itself.
