containerAppExtensionEntitlementsWithCompletion: failed with error: (null)

Question

Trying to authorize on watchOS. Getting this error:

2019-03-20 18:32:45.859857-0600 iRun WatchKit Extension[21129:1854743] [default] containerAppExtensionEntitlementsWithCompletion: failed with error: (null)

My Capabilities for both my App and my Watch Extension are both turned on for HealthKit.

There is a similar question to mine on here but no one has answered it. Can't find any way to interpret this error??

My code to authorize:

  if HKHealthStore.isHealthDataAvailable() {

            let healthStore = HKHealthStore()
            let heartRateQuantityType = HKObjectType.quantityType(forIdentifier: .heartRate)!
            let allTypes = Set([HKObjectType.workoutType(),
                                heartRateQuantityType
                ])

            healthStore.requestAuthorization(toShare: nil, read: allTypes) { (success, error) -> Void in
                if success == false {
                    print("Error")
                }
        }
        }

And for the AppDelegate.swift in my app:

func applicationShouldRequestHealthAuthorization(_ application: UIApplication) {
        let healthStore = HKHealthStore()
        healthStore.handleAuthorizationForExtension { (success, error) -> Void in

        }
    }
