Source code generation fails under 1.0.0-M1

Thank you for providing such a great tool! I also use it for my work. :)

When running under the following conditions, an error occurs, and the source code generation fails:

Version: 1.0.0-M1
Scala Version: 2.12.18 (intended for use with sbt-guardrail)
JDK: Corretto-17.0.11.9.1

(I have masked the type names.)

    FooBarType:
      type: string
      enum:
        - A
        - B
        - C
        - D
    foo_type:
      type: array
      nullable: false
      items:
        allOf:
          - $ref: '#/components/schemas/FooBarType'

sbt:my-project> guardrail
Error:Unknown type for the following structure (No type definition, class: io.swagger.v3.oas.models.media.ComposedSchema, .components.schemas.foo_type.items):
  Tracker(class ComposedSchema {

      }
  }, Vector(.components, .schemas, .foo_type, .items))
