Cloudflare - pmtiles file not loading

[kbatchu]

I uploaded a pmtiles file to an r2 instance on Cloudflare, configured a custom domain and created a worker with the code provided in the Protomaps docs for Cloudflare integration. But I am getting this error while loading the file through a web app.

I checked the url in postman and it returns a small chunk (148KB) which looks right.

The returned content looks appropriate.

I checked this url in the PMTiles viewer and get the same error message. What seems to be the problem?
Thanks,
Kiran

If you are using the cloudflare worker integration, than your endpoint /z/x/y.mvt is now transformed into a ZXY endpoint, not a .pmtiles anymore, so you should specify that ZXY URL in your frontend code; you don't need any PMTiles related libraries on the frontend at all.

Then shouldn't I set the extent on the source of the Raster layer which is of type 'XYZ' ?

[bdon]

Yes, you are right - I mixed them up. Set the extent on the raster source for the gray dots.

For what it's worth, this felt a bit subtle and I made the same mistake following the docs. I followed the PMTiles MapLibre setup (which adds the protocol for PMTiles) then the AWS guide (defining a lambda that serves XYZ tiles), but spent a while wondering why the lambda was trying to look up a XYZ tile for the initial PMTiles range request.

Maybe it would be useful to include a note about this in the AWS and Cloudflare setup? e.g., something as simple like "this will return XYZ tiles directly, so the PMTiles protocol shouldn't be used on the client using this setup" might be helpful

This is already outlined here: https://docs.protomaps.com/deploy/
And in the AWS setup under "make a test request": https://docs.protomaps.com/deploy/

I am hesitant to add documentation on how to use Z/X/Y URLs because that is redundant with existing MapLibre, Leaflet, etc documentation.

@bdon That's totally fair, most people will probably pick up on the URL format earlier and notice the difference (PMTiles protocol vs. XYZ depending on the guide). I wasn't familiar with PMTiles before this so I thought the same format would be used in both.
