Determining crash on HKObject _validateForCreation - ios

Question

While testing on device (Apple Watch) attempting to save an HKWorkout into HealthKit I am adding samples of distance samples, calories, heart rates and vo2Max to the workout. Unfortunately unlike this question I am not getting as detailed as a trace back...as far as I can tell it's crashing on adding a sample but I can't tell which sample it is or why?
Code:
private func addSamples(toWorkout workout: HKWorkout, from startDate: Date, to endDate: Date, handler: #escaping (Bool, Error?) -> Void) {
let vo2MaxSample = HKQuantitySample(type: HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.vo2Max)!, quantity: vo2MaxQuantity(), start: startDate, end: endDate)
var samples = [HKQuantitySample]()
for distanceWalkingRunningSample in distanceWalkingRunningSamples {
samples.append(distanceWalkingRunningSample)
}
for energySample in energySamples {
samples.append(energySample)
}
samples.append(vo2MaxSample)
samples.append(contentsOf: heartRateValues)
// Add samples to workout
healthStore.add(samples, to: workout) { (success: Bool, error: Error?) in
if error != nil {
print("Adding workout subsamples failed with error: \(String(describing: error))")
handler(false, error)
}
if success {
print("Success, samples have been added, workout Saved.") //WorkoutStartDate = \(workout.startDate) WorkoutEndDate = \(workout.endDate)
handler(true, nil)
} else {
print("Adding workout subsamples failed no error reported")
handler(false, nil)
}
}
}
