Error: SortDirection values must be an object with value names as keys about graphql HOT 5 CLOSED

I finally found the reason of the bug. I am using a monorepo and there were conflicts between versions of GraphQl (16.8 and 15.8). In graphQl-tools, there was a deprecation with the field isPossibleType which led to an invalid schema. The fix was to upgrade graphql at the root of the monorepo and it worked

Hi @TheMaximeBatandeoExperience, I can't reproduce this issue locally. Are you able to provide a full code-example which reproduces this issue?

from graphql.

Yes, thank you for your quick answer

import {getNeo4JSession} from "./neo4j";
import {Neo4jGraphQL} from "@neo4j/graphql";

export const neoSchema = async () => {
  try {
    const {driver} = await getNeo4JSession();
    const schema = new Neo4jGraphQL({
      typeDefs: `#graphql
    type Movie {
        title: String
        actors: [Actor!]! @relationship(type: "ACTED_IN", direction: IN)
    }

    type Actor {
        name: String
        movies: [Movie!]! @relationship(type: "ACTED_IN", direction: OUT)
    }
`,
      driver
    });
    const yogaSchema = await schema.getSchema();
    return yogaSchema;
  } catch (error) {
    console.error("Error initializing schema", error);
  }
};

I use it a nextJs 14 AppRouter. So i created a route api/graph/route.ts where my yoga server lives using the implementation in the yoga documentation

import { createSchema, createYoga } from 'graphql-yoga'
 
const { handleRequest } = createYoga({
  schema: await neoSchema()
    }
  }),
 
  // While using Next.js file convention for routing, we need to configure Yoga to use the correct endpoint
  graphqlEndpoint: '/api/graphql',
 
  // Yoga needs to know how to create a valid Next response
  fetchAPI: { Response }
})
 
export { handleRequest as GET, handleRequest as POST, handleRequest as OPTIONS } 

Also I tried with apollo server and same trouble.
I am not sure that it is relevant but from the beginning I always had a Typescript error with the schema provided by Neo4jGraphQl (with Apollo or Yoga)
Unable to assign 'GraphQLSchema | undefined' au type 'YogaSchemaDefinition<{}, {}> | undefined Missing isPossibleType

Hi @TheMaximeBatandeoExperience
Sorry, but the code you provided doesn't seem correct as it is invalid javascript (maybe a copy paste problem?).

Please refer to this example on how to set up a yoga server with Neo4j GraphQL (you can ignore the typedefs and the subscription on that example), I just checked that example and the js code should work.

For how to integrate yoga with NextJS you'll need to refer to either one of those projects.
