I don't know correct channel to post this question. I'll delete from getting started if it belongs only in spring. I'll delete from spring if it belongs only in getting started.

Okay I deleted from #spring as I found a language only solution.

data class ExampleProblem(
    val id: Long,
    val notNullableField: List<String> = emptyList() 
}

i.e. don't provide a secondary constructor use a default value.
