location.id null in MAURBackgroundGeolocation::onLocationChanged()

[Yermo]

I am most of the way through creating a NativeScript plugin for this library. I have the Android version working as I expect, however, it seems that in the iOS version the location id is always NULL in the onLocationChanged() callback.

See

background-geolocation-ios/BackgroundGeolocation/MAURBackgroundGeolocationFacade.m

Line 517 in 5149178

[postLocationTask add:location];

Shouldn't the location be persisted first then the onLocationChanged callback called with a valid locationId?
