setSourceProperty clusterMaxZoom for GeoJSONSource

[mfazekas]

Environment

• Xcode version: 14.0.1
• iOS version: 16.0
• Devices affected: Simulator/iPhone 14 Pro
• Maps SDK Version: 10.8.1, 10.9.0-beta.2

Observed behavior and steps to reproduce

I cannot change GeoJSONSource's clusterMaxZoom property on the fly

      style.setSourceProperty(for: "people", property: "clusterMaxZoom", value: 12.0)

Getting the following error:

MapboxMaps.StyleError(rawValue: "Cannot set property clusterMaxZoom for the source people")

Expected behavior

Update clusterMaxZoom on the fly.

Notes / preliminary analysis

Tried setting the value with NSNumber or just

      style.setSourceProperty(for: "people", property: "clusterMaxZoom", value: style.getStyleSourceProperty(forSourceId: "people", property: "clusterMaxZoom").value)

got same error

  }

    mapView = MapView(frame: view.bounds, mapInitOptions: myMapInitOptions)
    mapView.autoresizingMask = [.flexibleWidth, .flexibleHeight]

    self.view.addSubview(mapView)
    
    mapView.mapboxMap.onNext(.styleLoaded) { _ in
       var source = GeoJSONSource()

       source.clusterRadius = 20.0
      

       let mapboxMap = self.mapView.mapboxMap!

       try! mapboxMap.style.addSource(source, id: "people")

       try! mapboxMap.style.setSourceProperty(for: "people", property: "clusterMaxZoom", value: 12.0)

      layer.circleRadius = .constant(radius)
      layer.circleRadiusTransition = .init(duration: 2.0, delay: 0.0)
      layer.circleOpacity = .constant(0.5)
      
      try! mapboxMap.style.addLayer(layer)
