The OSM layer is a subclass of XYZ, and therefore has a constructor that
takes three options:
Parameters
name {String}
url {String}
options {Object} Hashtable of extra options to tag onto the layer
You have passed an object to the second option (url), and when it
tries to call the template replacement on that non-string, you get
an error.
Since the OSM layer is already a sphericalMercator layer, you can
simply remove the second argument to your OSM layer, and this should
solve this problem.
