Example Server does not show any tiles

[wielandb]

I used tilemaker to generate a .mbtiles file, and everything went well.
I now wanted to preview the tiles on the included ruby server, but no tiles show, just the red rectangles that I assume are placeholders for when there are no tiles.
Having no tiles in some areas is expected for me, as I only generated a file for germany. I used the provided example.json config file and the provided proccess.lua for generating the tiles. Also, curiously, the tile server reports a 200 for all tiles that I try to load, even when scrolling to areas that should not be covered.

I assume that when first loading the page, the map pans to an area that should be covered by the generated tiles.

What do I have to do to view my generated tiles?

Could you share the exact steps you took - i.e. where you downloaded the .osm.pbf from, the commands you issued, whether you altered the default config at all, etc.?

Of course, here are the commands I issued:

wget https://download.geofabrik.de/europe/germany/baden-wuerttemberg-latest.osm.pbf
wget https://download.geofabrik.de/europe/germany/bayern-latest.osm.pbf

cd path/to/tilemaker/server
ruby server.rb ~/tilemaker/out.mbtiles

My config file is this one and my lua-file is this one

This is the output of the server command, despite seeing nothing, a 200 OK seems to be returned on every file:

Here is what I am seeing:

Ah, I see. The config-example.json and process-example.lua files are just examples of how to structure these config files. They won't write much data to the tiles, and it won't be in the schema (=data layout) expected by the standard style file used by the Ruby server.

You should use config-openmaptiles.json and process-openmaptiles.json.
