Cannot use graphqlconfig to read latest graphql syntax correctly

[kenNg1]

graphql/graphql-js#1169 From graphql@^0.13.0 We separate multiple inherited interfaces with &. graphql-config@2.0.1 added support of graphql@^0.13.0 but this repository is still using graphql-config@^1.1.1 which makes it unable to read the new syntax e.g.

type Photo implements File & Node {
  id: ID!
  url: URL!
  height: Int!
  width: Int!
  images: [Image]
  caption: String
}

and we will get error like below when we use .graphqlconfig

Syntax Error: Cannot parse the unexpected character "&".

GraphQL request (435:28)
434:
435: type Image implements File & Node {
                                ^
436:   id: ID!

Please consider upgrading the graphqlconfig dependency to ^2.0.1 thanks.
