It's tough to say without seeing a full stack trace, but it's possible that you're using a GraphQLObjectType as the type of an input argument, rather than a GraphQLInputObjectType; http://facebook.github.io/graphql/#sec-Input-Objects explains why object types are disallowed as the types of arguments and why input objects are used instead.
Based on https://github.com/facebook/relay/issues/159, sounds like this is resolved.
Yes, it is. Thx!
Is the link above broken (the documentation one)? It doesn't send us anywhere, and I'm running into this same issue
