Description of the bug:
Valid URL for a Martin Vector Tile server (just built in the last week) does not display (or connect to Martin) in Maputnik. I built a Martin server which is serving up an MBTiles SQLite file created by the openmaptiles project. The URL to the Martin server is:

http://debian1:3000/jlptiles/{z}/{x}/{y}
or
http://localhost:3000/jlptiles/{z}/{x}/{y}

I have the URL working in QGis.

Steps to reproduce the behavior:

1. Launch just-updated/built Maputnik with:

jlpoole@debian1:/usr/local/src/maputnik$ npm run start -- --host 0.0.0.0

> [email protected] start
> vite --host 0.0.0.0

2. On the same machine as the Maputnik server and the Martin server, "debian1", load in Firefox the URL: http://debian1:8888/
3. Create a Vector XYZ server instance providing the URL to the Martin server: http://debian1:3000/jlptiles/{z}/{x}/{y}
4. Load the locally (debian1) saved JSON file: /home/jlpoole/MapLibre/local/202406141808_sprite_added.style (which is also exposed via an Apache server at: http://localhost/MapLibre/local..."
5. Global may or may not appear, but zooming into the state of Oregon which the mbtiles contains, nothing happens.

Here's the log from the Martin server when I start and stopped Maputnik https://pastebin.com/izbK012G

Style file or style URL:

Attaching zip of: 202406141808_sprite_added.style
I've used 202406141808_sprite_added.style in QGis, and it was because of some styles I wanted to alter/fix that compelled me onto Maputnik.

Anticipating the "Try it on Chromium", I launched Chromium and accessed the local URL: Maputnik did not even appear, just a black screen.

However, using a Gentoo Linux server and Google Chrome thereon, I am able to display Maputnik. However, when I add the datasource pointing to the martin server, nothing appears. I was able to display within the Gentoo Chromium the martin server's catalog and the request appears in the martin log. Yet, when I try refreshing Maputnik on the Gentoo Chromium to cause a query to the martin server, nothing happens and the martin server does not register any request.

Looking at the screen shot it looks like the layers do not match the data that your are serving.
But this is just a guess.
I would recommend to start using maputnik with something that works and slowly complicate things and understand what's not working and how to fix it.

Has anyone been able to use Maputnik specifying a data source served up by a local MapLibre Martin server?

[HarelM]

I'm sure martin is no different, but I was able to use go pmtiles and tileserver-gl.
I would advise to check the console log for errors.
