    val moshi = Moshi.Builder()
            .add(UuidJsonAdapter())
            .add(LocalDateJsonAdapter())
            .build()
    val json = SecurityMatchRequestJsonAdapter(moshi)
            .toJson(smr)

    println(smr)
    println(json)
}

works with moshi-kotlin 1.6.0
need to setup kapt for annotation processing
