}

@Serializable
data class Musics(
    val tag:Int? =null,
    @JsonInclude(value=JsonInclude.Include.NON_NULL)
    val title:String?="",
    val artist:String?="",
    val duration: String?="",
    val tagU:Int? =null
)

 override fun addMusic(music: Musics){
        transaction {
                Music.insert{
                    it[title]= music.title ?:""
                    it[artist]=music.artist?:""
                    it[duration]=music.duration?:""
                    it[tagU]=music.tagU?:0
                }
            }
    }

Looks like the call.receive line is failing - the request body cant be converted to a music object

Also you shouldn't have /add as your path - that is bad design - post /music is adding/creating
