Invalid Schema for optional field arguments on interface implementations

See original GitHub issue

Version and Environment Details

Operation system: OSX

IDE name and version: WebStorm 2020.1 EAP

Plugin version: 2.4.0

Expected Behaviour

interface Vehicle {
  name: String!
}

type Car implements Vehicle {
  name(charLimit: Int = 10): String!
}

This was, at one point, an invalid schema, but it was made valid 5 years ago. https://github.com/graphql/graphql-spec/pull/110 https://github.com/graphql/graphql-spec/issues/401

Actual Behaviour

graphql.schema.validation.InvalidSchemaException: invalid schema:
object type 'Car' does not implement interface 'Vehicle' because field 'name' has a different number of arguments

It does look like it’s straight from the library so I’ll create an issue there as well. https://github.com/graphql-java/graphql-java/issues/1932
