Hi , What's wrong with this data class?

@Entity(
        tableName = "template"
)
data class ListTemplate (
        @PrimaryKey(autoGenerate = true) var id: Long = 0L,
        @SerializedName("name") var name: String = "",
        @SerializedName("thumbnail") var thumbnail: String=  "",
        @SerializedName("category") var category: String = "",
        @SerializedName("totalAmount") var totalAmount: Long = 0L,
        @SerializedName("currency") var currency: String = ""
)

studio is throwing an error saying

Error:Type of the parameter must be a class annotated with @Entity or a collection/array of it.

data class looks good, but this error message not about data class, you use in some other code I suppose
