IntelliSense Error: "Unknown argument 'order' on field" Despite Schema Support

IntelliSense Error for Valid Field Argument in GraphQL Query (order on episodes)

Question

I'm experimenting with GraphQL for the first time and trying to understand the setup and tooling better. I’m using @graphql-codegen/client-preset and encountering an issue where IntelliSense in VSCode shows the following error:

Unknown argument "order" on field "ProgramName.episodes"

However, the query executes correctly, and the order argument is clearly defined in both the GraphQL schema and the generated TypeScript types.

Since I’m still learning, it’s possible I’m doing something wrong, but I’d appreciate any help in understanding what might be causing this.

Query Example

export const ProgramsWithEpisodesQueryDocument = graphql(`
  query ProgramsWithEpisodes($where: ProgramNameFilterInput) {
    programs(
      where: $where,
      order: { name: ASC }
    ) {
      items {
        id
        gid
        name
        episodes(order: [{ name: ASC }]) {
          id
          gid
          name
        }
      }
    }
  }
`);

Schema Snippet

type ProgramName {
  episodes(order: [EpisodeSortInput!]): [Episode!]!
  ...
}

input EpisodeSortInput {
  name: SortEnumType
  ...
}

Generated Type

export type ProgramName = {
  __typename?: 'ProgramName';
  episodes: Array<Episode>;
  ...
};

export type ProgramNameEpisodesArgs = {
  order?: InputMaybe<Array<EpisodeSortInput>>;
};

Codegen Configuration

const config: CodegenConfig = {
  schema: 'http://127.0.0.1:7003/graphql',
  // schema: './schema.graphql',
  documents: ['src/**/*.tsx', 'src/server-api/**/*.ts'],
  ignoreNoDocuments: true,
  generates: {
    'src/graphql/': {
      preset: 'client',
    },
    './schema.graphql': {
      plugins: ['schema-ast'],
      config: {
        includeDirectives: true
      }
    }
  }
}

export default config;

tsconfig.json Plugin Section

"plugins": [
  {
    "name": "next"
  },
  {
    "name": "@0no-co/graphqlsp",
    "schema": "./schema.graphql"
  }
]

devDependencies

• @graphql-codegen/cli: ^5.0.5
• @graphql-codegen/client-preset: 4.8.0
• @graphql-codegen/typescript: ^4.1.6

Setup

• VSCode with GraphQL extension and graphql-codegen

Question

Is there something I'm missing in my GraphQL setup or codegen configuration that could cause IntelliSense to incorrectly flag the order argument on the episodes field?

The query works fine, and the schema and types appear to be correctly generated. I’m trying to understand if this is a tooling issue or a mistake in how I'm approaching this.

Any guidance would be appreciated.

I found the issue — IntelliSense was not working because the VSCode extension was not picking up the newly generated schema.

Running the codegen or reloading the schema in the GraphQL plugin wasn’t enough.

Solution:

A full restart of VSCode (not just reloading the window or the terminal) fixed the problem. After restarting, IntelliSense correctly recognized the order argument on episodes.

Leaving this here in case someone else runs into the same issue.
