Remove watchHeadingAsync listener from Expo location API

Please provide the following:

  1. SDK Version: 39
  2. Platforms(Android/iOS/web/all): Android && IOS

I am using the Location API from Expo for a compass, the app uses the Location.watchHeadingAsync and the watchPositionAsync for orientation. The problem that I am facing is the removal of the listeners, the watchPositionAsync gets deleted successfully, but not the watchHeadingAsync listener. The error that I get is: ‘this.HeadingListener.remove is not a function’. This is the code that I am using:

componentDidMount() {
    if(this.getPermission()) {
      this._subscribe();
      this._getLocation();
    }
  }

  getPermission = async() => {
    let { status } = await Location.requestPermissionsAsync();
      if (status !== 'granted') {
        return false;
      } else {
        return true;
      }
  }

  componentWillUnmount() {
    this.HeadingListener.remove()
    this.LocationListener.remove()
  }

  _subscribe = async() => {
    this.HeadingListener = Location.watchHeadingAsync((response) => {
      //console.log(response)
      this.setState({Heading: response.magHeading, Accuracy: response.accuracy })
    })
  }

  _getLocation = async() => {
    this.LocationListener = await Location.watchPositionAsync({accuracy: 6, timeInterval: 2000, distanceInterval: 0}, (response) => {
      console.log('Homescreen location')
      this.setState({lat: response.coords.latitude})
      this.setState({long: response.coords.longitude})
  })
  }
