     * @exampleMarkdown
     * ## `errorHandlingClient`
     * An error handling client is a client which prevents the user from reading a `null` used as a placeholder for an error in a GraphQL response.
     * The client may do so by throwing when an errored field is accessed (as is the case for [`graphql-toe`](https://github.com/graphile/graphql-toe)),
     * or when a fragment containing an error is read (as is the case for Relay's `@throwOnFieldError` directive),
     * or by preventing any data from being read if an error occurred (as with Apollo Client's `errorPolicy: "none"`).
     *
     * When using error handling clients, a semantic non-nullable field can never be `null`.
     * If a semantic non-nullable field's value in the response is `null`, there must be a respective error.
     * The error handling client will throw in this case, so the `null` value is never read.
     *
     * To enable this option, install `graphql-sock` peer dependency:
     *
     * ```sh npm2yarn
     * npm install -D graphql-sock
     * ```
     *
     * Now, you can enable support for error handling clients:
     *
     * ```ts filename="codegen.ts"
     * import type { CodegenConfig } from '@graphql-codegen/cli';
     *
     * const config: CodegenConfig = {
     *   // ...

     *       },
     *     },
     *   },
     * };
     * export default config;
