Plugin gives schema validation errors for values of an extended scalar type

[luispollo]

Given the following directive in a schema:

scalar JSON

"Custom Annotation"
directive @annotate(
  name: String!
  inputs: JSON
) repeatable on OBJECT | FIELD_DEFINITION | INPUT_OBJECT | INPUT_FIELD_DEFINITION

The plugin will flag the usage of the @annotate directive as invalid syntax in the usage site, for example:

type MyType {
  prop: String @annotate(name: "MyAnnotation", inputs: {value: ["test"]})
}

Errors reported:

• 'prop' uses an illegal value for the argument 'inputs' on directive 'annotate'. Argument value is of type 'ObjectValue', expected a scalar
• Unknown field "value" on input type "JSON"

Note that JSON is an extended scalar I've registered in my application. I'm guessing the problem has something to do with the fact that it requires registration at runtime, so I'm not sure how that would work with an IntelliJ plugin.

To Reproduce

1. In an IntelliJ project, create a GraphQL schema file recognized by the plugin
2. Add the definitions above
3. The editor will highlight the usage site with a syntax error

Expected behavior No syntax errors are reported.

To add to the above description, the main issue is the fact that JSON is not recognized as a scalar when used with graphql-extended-scalars library : https://github.com/graphql-java/graphql-java-extended-scalars
