WebTileLayer: Can't fetch tiles from external URL

Hi there!

I'm trying to add a WebTileLayer to my map, however the resulting URL when fetching tiles isn't correct.

My code:

const webTileLayerFromUrl = new WebTileLayer({

urlTemplate:"https://maps2.wien.gv.at/basemap/geolandbasemap/normal/google3857/{z}/{x}/{y}.png",

});

esriMap.basemap = new Basemap({

baseLayers: [webTileLayerFromUrl],

});

Example of correct URL for these map tiles (works): https://maps2.wien.gv.at/basemap/geolandbasemap/normal/google3857/19/181789/285965.png

A URL generated by my code when run (does not work): https://maps2.wien.gv.at/basemap/geolandbasemap/normal/google3857/19/288513/154195.png

I'm assuming I've done something wrong when creating my WebTileLayer, but I'm not quite sure how to fix this.

Things I've tried so far:

- Swapping the {x} and {y} in the urlTemplate (wasn't the issue)

- The geolandbasemap uses a tile size of 256. I tried adding a tileInfo with size = [256, 256]. That did not help either.

- Swapped the urlTemplate for another, to make sure there was no issue with my code itself: E.g. https://a.tile.openstreetmap.org/{z}/{x}/{y}.png loads just fine.

If anyone has any advice, I would greatly appreciate it 🙂

Update: Ended up finding an Esri Vector Tile Service for the same basemap, which I'll use instead of the WebTileLayer. Unfortunately I'm not sure what the solution would have been if I continued to investigate.
