title: gqlgen - DirectiveResolver not exported by package generated
body: <p>I am new to GraphQL, gqlgen library. Tried running <code>go run github.com/99designs/gqlgen init</code> command but getting <code>validation failed: packages.Load: C:\Users\Aylin\Desktop\gqlgen-tutorial\graph\prelude.resolvers.go:19:44: __DirectiveResolver not exported by package generated</code> error. This is the first step of the project setup and is not supposed to cause any errors. Anyone had the same problem and knows how to fix it? Thanks</p>
