Description
Installed Waymarkedtrails database according to this manual: https://github.com/waymarkedtrails/waymarkedtrails-backend/ (with the whole planet as data soruce like in the manual)
All went fine until creating additional route databases for hiking with the command 'wmt-makedb hiking import' - then, after some hours, an error occured and the script died:

Tested the same install with a small .osm.pbf file (https://download.geofabrik.de/africa/canary-islands-latest.osm.pbf) and all was good.
Guess there are some issues in teh source which need to handled?
Would be nice if you check on this issue.
