NullValue{} in generated code

[mores]

I downloaded schema.json from my service provider. I used graphql-introspection-json-to-sdl to convert it to schema.graphql I used graphqlcodegen-maven-plugin ( 1.61.5 ) to generate java objects. At this point the objects will not compile - it complains about: private Integer maximum = NullValue{}; I get this same error when using gradle: id "com.netflix.dgs.codegen" version "6.3.0" and "7.0.3"

Is this a bug with the codegen or a lack of configuration ? I did look over: https://netflix.github.io/dgs/generating-code-from-schema/

an example schema.graphql that creates this issue is:

input QuantityRuleInput { increment: Int! maximum: Int = null minimum: Int! variantId: ID! }
