I'm desperately trying to swap out my basemap in cartodb.js.
Here's the snippet of code, the part I switched out successfully with some basemaps is in bold: L.tileLayer('https://dnv9my2eseobd.cloudfront.net/v3/cartodb.map-4xtxp73f/{z}/{x}/{y}.png'
When I inspect element or go here, I get a wide variety of options, like so: http://leaflet-extras.github.io/leaflet-providers/preview/
For example, this works: L.tileLayer('http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{z}/{y}/{x}'
But this doesn't:
L.tileLayer('http://{s}.{base}.maps.cit.api.here.com/maptile/2.1/{type}/{mapID}/hybrid.day/{z}/{x}/{y}/{size}/{format}?app_id={app_id}&app_code={app_code}&lg={language}'
How do I swap out this code??
