BUG: Map preview fails when 'center' property is not present in metadata about mbtileserver HOT 7 CLOSED

You can open the tileset using a SQLite viewer like DB Browser for SQLite, then navigate to the metadata table, add an entry for center (longitude, latitude, zoom), then save it. Zoom is arbitrary; I often use the lowest zoom of a tileset.

@ItalyPaleAle it sounds like the issue is that the metadata table for your tileset does not contain an entry for center, which is optional according to the TileJSON spec - but I must have always expected it to be present within the maps. Most tools that create tiles produce a metadata entry for center. Out of curiosity, how did you create your tileset?

As a quick fix, you can add an entry for center to your tileset(s) and restart the server.

Is this problem showing up for an image tileset or a vector tileset?

Thanks for the quick response and for pinpointing the issue quickly!

I'm very new to working with TileJSON and maps. I was trying with a map I created with tilemaker from OSM data. It's a vector tileset.

Let me look into how to add a center property - I'm really brand new to this :)

I submitted a PR that fixes the issue!

Thanks for reporting this! I just pushed changes to main branch that fixes this. If that doesn't fix the problem for you, please reopen this issue.
