anyOf does not work

[NyxCode]

In my spec, I am using anyOf:

schemas:
  ...
  SuperType:
    type: object
    anyOf:
      - $ref: "#/components/schemas/SubType1"
      - $ref: "#/components/schemas/SubType2"
    discriminator:
      propertyName: type
      mapping:
        subType1: "#/components/schemas/SubType1"
        subType2: "#/components/schemas/SubType2"

This is just rendered as an empty JSON object ({}).
I tried to get around this by manually specifying examples, but they don't seem to work yet for request bodies.
Is there any workaround for this? Would appreciate some advice since this is a blocking issue for me right now.
