usage error #196

Hi, I've been trying to follow the LatLong Example but I keep hitting the following issue

java.lang.NullPointerException: Cannot invoke "com.dlsc.gmapsfx.javascript.IWebEngine.executeScript(String)" because "com.dlsc.gmapsfx.javascript.JavascriptRuntime.engine" is null

Could I get some guidance on how to rectify this, since I have no idea where to begin

below is the entire error log

Are you able to get com.dlsc.gmapsfx.MainApp to run? It's been a while since I looked in here but the usual cause of issues like that was not waiting until the mapInitialised listener is called before taking action. Are you running the example as is? I admit I haven't tried it since it was changed to an FXML example, and I have no idea how that works with delayed activation.
