Description
I'm trying to generate a code that has two arrays and both of them has the same type.
But instead both of them being generated as arrays the second one is an object Any
data class Boxes (
@field:JsonProperty("firstBox")
val firstBox: kotlin.collections.List<kotlin.String>? = null,
@field:JsonProperty("secondBox")
val secondBox: kotlin.Any? = null
)

Research direction
No repository file, test, or generation command is named. Start by reproducing the issue with the supplied OpenAPI 3.1 schema using the Kotlin generator, then locate the generator logic and tests covering array properties. Done means both firstBox and secondBox are generated as lists of Size rather than the second property becoming Any.
