Would have to be on your end, the image is high res for me.

You are using the function wrong.
tilemap.get_tile(url, layer, x, y)
You need to provide a url to the tilemap you want to change.
Here is the API for the tilemap
It should be something like tilemap.get_tile("/go3#my_tile_map, "layer1", x_tile, y_tile)
Hmm, I am on an iPad currently.
