Types are generated twice in v3, making them all duplicated.

Title. In previous v2 versions there were no issues with duplicate types, but now when trying v3 it happens. This is the config:

import type { CodegenConfig } from '@graphql-codegen/cli';

const config: CodegenConfig = {
  schema: 'http://localhost:11500/graphql',
  documents: 'api/queries/**/*.graphql',
  ignoreNoDocuments: true,
  generates: {
    'api/gql/': {
      preset: 'client',
      plugins: ['typescript'],
      config: {
        maybeValue: 'T | null | undefined',
      },
    },
  },
};

export default config;

Anyone else who's run into this issue? In v3? I found one other thread but that was using the yml config, which worked, so doesn't help here sadly.

Hey, @PhilipAngelinNE You should remove the 'typescript' plugin from the plugins array. The client preset already automatically applies this plugin.

import type { CodegenConfig } from '@graphql-codegen/cli';

const config: CodegenConfig = {
  schema: 'http://localhost:11500/graphql',
  documents: 'api/queries/**/*.graphql',
  ignoreNoDocuments: true,
  generates: {
    'api/gql/': {
      preset: 'client',
-     plugins: ['typescript'],
+     plugins: [],
      config: {
        maybeValue: 'T | null | undefined',
      },
    },
  },
};

export default config;

Thanks for quick reply, that did fix it. But now the watch script only generates that one file, the other 3 are gone, including the one with the helper function. Is there a plugin I need to use for those?

Edit: Nevermind after another restart it works as normal again. Thanks for the help once again!

There is #8963 for the latter issue 😁
