Hello,
I'm getting mixed SRID geometries error in funcion: getDatabaseQuery: function(bbox) in tile.js
Do you have any idea why?

this is the generated query:

Thank you very much for your help,

This error might be happening because osm2pgsql uses EPSG:3857 (--merc option and default behaviour) for a longer time, but node-tileserver still used the deprecated EPSG:900913.

Now node-tileserver was updated so that it expects the geometries in the database stored as EPSG:3857. See #122 and #129 for further details.
