How can the property example for discriminator be done? - kotlin

Question

I'm generating swagger description with openapi annotations.
There is a case with polymorphic dto's with a discriminator property type that I can't handle:
#JsonTypeInfo(
use = JsonTypeInfo.Id.NAME,
include = JsonTypeInfo.As.PROPERTY,
property = "type"
)
#JsonSubTypes(
JsonSubTypes.Type(value = ListValue::class, name = "in"),
JsonSubTypes.Type(value = ExactValue::class, name = "is")
)
abstract class CompositeValue
and two subclasses:
#JsonTypeName("is")
data class ExactValue(
#get:Schema(
description = "Single condition value.",
example = "2"
)
val value: String
) : CompositeValue()
#JsonTypeName("in")
data class ListValue(
#get:Schema(
description = "Multiple condition value.",
example = "[2, 4, 6]"
)
val value: List<String>,
) : CompositeValue()
Openapi generates swagger example type field example "string", nut i expect one of two available values (is / in) to be there:
"filters": [
{
"name": "value",
"value": {
---> "type": "string", <---
"value": "2"
}
}
]
I couldn't find any solution (annotation or wmth) which I can use to make openapi to make a correct property example of type. Expected to use some jackson annotation but found nothing about it...
How such a case can be handled?
