[OSM-dev] Strange 412 error on relation upload / reason: integrity problem

[Frederik Ramm]

Hi,

   I had this once in the past already, and it happened again today. A 
perfectly valid looking relation returns a 412 error on upload. You 
check all the ways in the relation, they all seem to exist. You look at 
the ruby code and find that the relation upload also verifies the 
integrity of the ways (maybe unnecessarily...) and you check those. You 
find that one of the ways - in my case, way #23570555 - references a 
deleted node (#25934779).

You check the history and find that the most recent version of that way 
present in the history tables does *not* reference the deleted node.

So, for some reason, the node seems to have been deleted from the way, 
the history table was updated, but the current table wasn't.

Bye
Frederik
