data/schema.go:44: cannot use func literal

[johanoskarsson]

Attempted to follow the instructions but I get the following error. I assume something changed in graphql-go?

$ go get -v

I have also encountered the same problem

I solved the problem，this is my code.
TypeResolve: func(p graphql.ResolveTypeParams) *graphql.Object {
switch p.Value.(type) {
case *User:
return userType
case *Widget:
return widgetType
}
return nil
}
