Puzzling error inserting data into HKWorkoutRouteBuilder in watchOS 4 Beta 4

Question

When I insert route data into HKWorkoutRouteBuilder I get the following error:

The connection to service named com.apple.healthd.server was interrupted, but the message was sent over an additional proxy and therefore this proxy has become invalid

Here's a code snippet.

    workoutRouteBuilder.insertRouteData(filteredLocations) { (success, error) in
        if !success {
            print("inserting route data failed with error: \(String(describing: error))")
        }
    }

I patterned by impelementation from the Speed Sloth example.

Any insights would be appreciated!

UPDATE: Here's some more info from the watch logs. Looks like some sort of permission issue, but I haven't been able to track it down yet:

Answer 1

I had the same problem. You need to ensure that you request authorisation from the user for:

// Objective C
[HKSeriesType workoutRouteType]

// Swift
HKSeriesType.workoutRoute()

Answer 2

Don’t forget to add request of WorkoutRoute for HKHealthStore at AppDelegate

Workout Route does not work with Simulator, and only works with some HKWorkoutActivityType like .walking, .running on OS4

private func requestAccessToHealthKit() {

    let healthStore = HKHealthStore()

    let allTypes = Set([HKObjectType.workoutType(),
                        HKObjectType.quantityType(forIdentifier: .activeEnergyBurned)!,
                        HKObjectType.quantityType(forIdentifier: .distanceWalkingRunning)!])
    if #available(watchOS 4.0, *) {
        allTypes.insert(HKSeriesType.workoutRoute())
    }
    healthStore.requestAuthorization(toShare: allTypes, read: allTypes) { (success, error) in
        if !success {
            print(error?.localizedDescription ?? "")
        }
    }
}

Answer 3

The connection to service named com.apple.healthd.server was interrupted, but the message was sent over an additional proxy and therefore this proxy has become invalid

Seeing this message indicates that the system process handling the request has crashed or exited. You should file a bug with Apple. Look for healthd crash logs and include them.
