Hello,

I have declared following schema

type Person {
  name: ID!
  born: Int
  actedIn: [Movie] @relation(name:"ACTED_IN")
}
type Movie {
  title: ID!
  released: Int
  tagline: String
}
type Query {
  person : [Person]
}

Running the following query

{
  person(filter: {name_starts_with: "L"}, orderBy: "born_asc", first: 5, offset: 2) {
    name
    born
    actedIn(first: 1) {
      title
    }
  }
}
Trying out the same example provided in https://github.com/neo4j-graphql/neo4j-graphql-java

String schema = getResourceFileAsString("neo4j.graphql");

GraphQLSchema schemagql = SchemaBuilder.buildSchema(schema);

Translator t = new Translator(schemagql);
List<Cypher> x = t.translate(query);

x.stream().forEach(c->System.out.println(" Test -->"+c.getQuery()));

I am getting following error

org.neo4j.graphql.InvalidQueryException: Validation error of type WrongType: argument 'orderBy' with value 'StringValue{value='born_asc'}' is not a valid '_PersonOrdering' - Expected AST type 'EnumValue' but was 'StringValue'. @ 'person'

Am i doing something wrong?

It is an enum not a string. GraphQL used to be more lenient before allowing strings also in places for Enums,

just remove the double quotes around born_ASC
