Not generator custom directives at using 'schema-ast'

[jungpaeng]

After declaring the custom directive, I ran codegen.
This is the graphql code I ran.

directive @rest(url: String) on FIELD_DEFINITION

scalar Date
scalar DateTime
scalar Currency

interface Node {
  id: ID!
}

type PageInfo {
  hasNextPage: Boolean! @deprecated(reason: "Use `hasNextPage` instead.")
  hasPreviousPage: Boolean! @rest(url: "a")
  startCursor: String!
  endCursor: String!
  uploadDate: Date
}

After schema-ast runs, the rest directive I declared is gone.
like this.

directive @rest(url: String) on FIELD_DEFINITION

scalar Currency

scalar Date

scalar DateTime

interface Node {
  id: ID!
}

type PageInfo {
  endCursor: String!
  hasNextPage: Boolean! @deprecated(reason: "Use `hasNextPage` instead.")
  hasPreviousPage: Boolean!
  startCursor: String!
  uploadDate: Date
}

I want rest directive added.
This is my codegen config file. Anything I'm missing?

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

const config: CodegenConfig = {
  overwrite: true,
  schema: ['src/relay/schema/schema.graphql'],

  generates: {
    'src/relay/__codegen__/schema.graphql': {
      plugins: ['schema-ast'],
    },
  },
};

export default config;

Hi @jungpaeng,

schema-ast cannot print your Schema directives due to GraphQL introspection limitations: graphql/graphql-spec#300
