Kotlin Making Purchases. DSK v4.6.1

Hello,

My code below gets the following build errors.

1. None of the following functions can be called with the arguments supplied.

2. Cannot infer a type for this parameter. Please specify it explicitly.

I am copying from the Android set up guide and can’t see what I am doing wrong.  Any guidance would be greatly appreciated.

fun attemptPurchase(inActivity: Activity, forPackage: Package) {    Purchases.sharedInstance.purchasePackage(inActivity, forPackage,        onError = { error, userCancelled -> println("Error ${error.localizedMessage}")        },        onSuccess = { product, customerInfo ->        }    )}
