我无法将JSON数组转换为GroupModel数组。以下是我使用的JSON：

[{
  "description":"My expense to others",
  "items":["aaa","bbb"],
  "name":"My Expense"
 },
 {
  "description":"My expense to others","
  items":["aaa","bbb"],
  "name":"My Expense"
 }]

而GroupModel类是：

class GroupModel {
    var name: String? = null
    var description: String? = null
    var items: MutableList<String>? = null

    constructor(name: String, description: String, items: MutableList<String>) {
        this.name = name
        this.description = description
        this.items = items
    }
}

并尝试以下代码会导致Exception：

com.google.gson.JsonSyntaxException：java.lang.IllegalStateException：预期为BEGIN_OBJECT，但位于第1行第2列路径$ BEGIN_ARRAY

代码：

var model = gson.fromJson<Array<GroupModel>>(inputString, GroupModel::class.java)
