Firebase creating nested object on POST

Question

I am trying to HTTP POST a Treasure to a Firebase Real Time Database(2) using Micronaut's RxHTTP (1).

data class Treasure
(
    val treasureId : String? = null,

    val name : String,

    val description: String,

    val amount : Double,

    val lat : Double,

    val lng : Double
)

@Client("\${treauser.trasures.url}")
interface TreasureRepository : CreateTreasurePort
{
    @Post("/Treasure.json")
    override fun add(treasure : Treasure)
}

It posts but for some reason it nesting the object under uuid.

I do not want treasure to be there, I just want all five properties under the UID.

Answer 1

Solved by adding the @Body¹ annotation.

@Client("\${treauser.trasures.url}")
interface TreasureRepository : CreateTreasurePort
{
    @Post("/Treasure.json")
    override fun add(@Body treasure : Treasure)
}
