Cannot initate osm2pgsql.mark_way with Lua flex import

[Weltstaat]

Hi All,

I'm trying to get relation tags into a table of osm highways using the Lua flex import. I mainly relied on this example: https://www.grulic.org.ar/~mdione/glob/posts/bus-routes-with-osm2pgsql-flex-backend/

However the script fails when calling osm2pgsql.mark_way

I get the error message: attempt to call a nil value (field 'mark_way')

I have the suspicion it has something to do with my osm2pgsql setup.

Any ideas on this?

Thanks!

That script is using an old version of osm2pgsql. mark_way is not available any more. See https://github.com/openstreetmap/osm2pgsql/blob/master/flex-config/route-relations.lua for a working example how this is done these days.
