GraphQL makes front end work easier because FE folks can't seem to handle the complexity involved in making multiple calls to a backend. GraphQL moves that complexity somewhere else (ie: the backend).

From a BE POV GraphQL makes things more difficult because the failure behavior is more complicated. If a failure occurred in the FE then the FE presumably knows what to do. If a failure occurs in a graphql call chain it's unclear what the FE would like to happen, and the FE developer is probably clueless as to what they want, since the structure has been abstracted away.
