Enable pmtiles overzooming?

[chasedawson]

I'm serving a .pmtiles archive through s3, lambda, and cloudfront to provide source vector tile data to a map using Mapbox GL JS. I can't get the map to overzoom the vector tile data, however. If I just upload my .pmtiles archive to the pmtiles.io viewer, I can interact with the data past the max zoom, yet when it's served via my architecture my mapping application won't show zoom levels beyond the maxzoom of the tileset. Any suggestions on how to get overzooming working with my setup?

in Mapbox/Maplibre GL the sources object may look like:

'abc':{'tiles':['https://example.com/tileset/{z}/{x}/{y}.mvt']}

That does not have a maxzoom so it will not over zoom properly. You can either add:

'abc':{'tiles':['https://example.com/tileset/{z}/{x}/{y}.mvt', 'maxzoom': 15]} if you know your maxzoom, or you can use TileJSON:

'abc':{'url':'https://example.com/tileset.json'} (note url instead of tiles)

This will determine the maxzoom automatically but requires you to set the public hostname in the Lambda code.
