Hi, I'm using this script and it was woking in the past, but I have an error when executing /app/src/build/utils/update.php --import-diff xxx.osc.gz

Processing: Node(80k 20.0k/s) Way(0k 0.00k/s) Relation(0 0.00/s)DB writer thread failed due to ERROR: result COPY_END for planet_osm_nodes failed: ERROR:  duplicate key value violates unique constraint "planet_osm_nodes_pkey"
DETAIL:  Key (id)=(434418828) already exists.
CONTEXT:  COPY planet_osm_nodes, line 675

I was looking about the error and it seems to be external to the script but I would like to ask if you know anything about it?

Thanks

Sorry, did not happen here, yet.
