Convert to list of data class object from JSON string using Gson?

Question

I have JSON string as below

var purchases = "[{\"contentId\":\"861723b2-78e4-42ea-8479-40fa0850c314\",\"purchaseType\":\"RENT\"},{\"contentId\":\"138bc762-b539-4749-8706-de2f0eea4b61\",\"purchaseType\":\"PURCHASE\"}]"

I am trying to convert it into list of data class objects

val userPurchases: List<UserPurchases> = Gson().fromJson(purchases,List<UserPurchases>)

This is my data class

data class UserPurchases(
    val contentId: String,
    val purchaseType: String)
