Creating a simple map using a given map provider does not work in unfolding map

UnfoldingMap map;

AbstractMapProvider provider5;
void setup() {
  size(800, 600, P2D);
  smooth();
  provider5 = new OpenStreetMap.OpenStreetMapProvider();
  map = new UnfoldingMap(this,provider5);
}

void draw() {
  map.draw();
}

For the above code, the map does not show up and only to get some error messages. On the other hand, if I delete provider5, then it works. Could anyone let me know how to fix it?

I also tried the following, and it does not work either.

/* An application with a basic map.*/

int totalFrames = 3600;
Location center = new Location(62,10);
Integer zoom_start = 9;

UnfoldingMap map;
AbstractMapProvider provideru;
String provideruAttrib;
String attrib;
Float attribWidth;



void setup() {
  size(1000, 1000, P3D);
  smooth();
  provideruAttrib = "Google Maps";
  provideru = new Google.GoogleMapProvider();
  map = new UnfoldingMap(this,provideru);
  MapUtils.createDefaultEventDispatcher(this, map);
  
  map.zoomAndPanTo(zoom_start, center);
}

void draw() {
  map.draw();
}

The problem is that for some reason the access to the providers you give is not working. As for why… i tried going through the whole Code on Github, but the only thing that should happen is to use the mercatoProjection with a specified location… so i don‘t even see where the url would even be loaded…

All i can tell you, is to try and use different Providers and see if others work… or not set a provider for now and only add one later on, to see if maybe something else is the problem.

Yes, this should work.

Which version of Unfolding Maps are you using? What are the error messages you are getting?
