I am using firebase and this is my data class definition:

```
data class ClaimOrder(val address: String? = null,
                  val amount: Long = 0L,
                  val isProcessed: Boolean = false,
                  val onCreate: kotlin.Any? = ServerValue.TIMESTAMP)

```

however on logs I am seeing following warning: `W/ClassMapper: No setter/field for isProcessed found on class com.guness.bitfarm.service.models.ClaimOrder`

I have tried `@SerializedName("isProcessed")` but no luck.
