I have been following this guide https://www.apollographql.com/docs/angular/recipes/webpack/ but I am getting this error when I execute ng serve:

ERROR in ./src/app/shared/queries.graphql 1:6

Module parse failed: Unexpected token (1:6)

You may need anappropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

query supplierByName($value: String) { | Supplier(filter: { name: $value }) { | name

this is my angular.json file:
