我尝试使用www.example.com API创建一个应用程序walt.id，在该应用程序中，我收到一个错误，指出变量的类型应为kotlin.collections.List<kotlin.String>，但实际上却是java.util.ArrayList，尽管变量的类型正确：

@Json(name = "@context") 
var context: List<String>? = listOf("https://www.w3.org/2018/credentials/v1"),

我想知道这是Kotlin问题还是Walt.idAPI问题，因为它的实现不可用。变量是模型的一部分，传递给转换对象的方法：

package model

import com.beust.klaxon.Json
import id.walt.vclib.model.*
import id.walt.vclib.registry.VerifiableCredentialMetadata
import java.time.LocalDate

data class EHIC(
    @Json(name = "@context") 
    var context: List<String>? = listOf("https://www.w3.org/2018/credentials/v1"),
...

当我试图调用转换EHIC对象实现的方法时，我得到了以下错误：

Exception in thread "main" com.beust.klaxon.KlaxonException: Unable to instantiate VerifiableAttestation:

我还尝试将变量写为：

@Json(name = "@context") var context: kotlin.collections.List<kotlin.String> = listOf("https://www.w3.org/2018/credentials/v1"),

但它仍然会抛出同样的错误。
我为我糟糕的英语和含糊不清道歉，我非常疲惫，需要睡眠。帮助是非常感激的，谢谢。
