Describe the bug

To Reproduce Steps to reproduce the behavior:

extend type Subscription {
  authenticated: String @authenticated
}

const typeDefs = `
  directive @authenticated on FIELD_DEFINITION
`;

function transformer(openidConfigurationUrl: string) {
  return (schema: GraphQLSchema) =>
    mapSchema(schema, {
      [MapperKind.OBJECT_FIELD]: (
        fieldConfig: GraphQLFieldConfig<any, IamGraphqlServerContext, any>,
      ) => {
        const options = getDirective(schema, fieldConfig, "authenticated")?.[0];
        if (!options) return fieldConfig;

        const { resolve = defaultFieldResolver } = fieldConfig;
        fieldConfig.resolve = async (source, args, context, info) => {
          console.log("@authenticated");
          const idTokenPayload =
            await getIdTokenPayloadFromContext(openidConfigurationUrl)(context);
          if (!idTokenPayload) throw new Error401();

          context.idTokenPayload = idTokenPayload;

          return await resolve(source, args, context, info);
        };
        return fieldConfig;
      },
    });
}

  Subscription: {
    authenticated: {
      subscribe: async (_, __, context) => {
        console.log("subscribe authenticated", context.idTokenPayload, context.connectionParams);
        return (async function* () {
          for (const i of [0, 1, 2]) {
            yield { authenticated: "authenticated" };
          }
        })();
      },
    },
  },

Expected behavior console.log("@authenticated"); should be executed before console.log("subscribe authenticated", context.idTokenPayload, context.connectionParams); But console.log("@authenticated"); is executed after every emitted value

Environment:

• OS: Windows 10
• @graphql-tools/...: 10.3.1
• NodeJS: 20.14.0
