In kotlinx , do I need to write serialization strategy for each List<CustomClass> inside other class?

[Dominaezzz]

No you don't have to.

[Dominaezzz]

As long as CustomClass has been marked as @Serializable.

[Juanoterocas]

but when I try to accea to that List throws an exception

n't locate argument-less serializer for class null. For generic classes, such as lists, please provide serializer explicitly.

[Dominaezzz]

Is this in Ktor?

[Juanoterocas]

no. kotlinx directly

[Dominaezzz]

Which kotlinx library?

[Juanoterocas]

kotlinx-serialization

[Dominaezzz]

Are you using Json.parse("")?

[Juanoterocas]

override fun< T> result(clazz : KSerializer<T> ): T {
return Json.nonstrict.fromJson(clazz,statusResponse.data!!)

}

[Dominaezzz]

You'll have to pass in CustomClass.serializer().list.

[Juanoterocas]

where?

[Dominaezzz]

result(CustomClass.serializer().list)?

[Juanoterocas]

is into another class

@Serializable
data class User(
var id: Long?,
var email: String?,
var lastName: String?,
var username: String?,
var name: String?,
var password: String?,
var phone: String?,
//var origin: String?


@ContextualSerialization var registrationDate:Date? = null,


val userRoles :List<Role>,
@ContextualSerialization var birthday: Date?= null

)

[Dominaezzz]

Oh

[Dominaezzz]

I'm guessing you've already marked Role class with @Serializable, so I'm not sure why this doesn't work.

[Dominaezzz]

Might get more help in #serialization .
