GraphQL : the object name is defined in resolvers, but not in schema

Question

I want to define a mutation using graphql.

My mutation is getting an object as argument. So I defined the new Object in the schema and in the resolver using GraphQLObjec

Answer 1

In my case it happens because there is inconsistent in schema for non-null. in my mutation I don't have the non-null mutation while in the object schema it has non-null mutation.
