NPE when creating dataitem: Cannot invoke "javax.json.JsonObject.getString(String)" because the return value of "javax.json.JsonObject.getJsonObject(String)" is null

[mnalis]

I've right-clicked on tag building:wikipedia, choose Create new dataitem for building:wikipedia, filled in description and applicable types and confirmed, and the error was thrown. I've create several other dataitems successfully in that JOSM session before that one.

At the time, ​https://wiki.openstreetmap.org/wiki/Special:ItemByTitle/wiki?site=wiki&page=Key%3Abuilding%3Awikipedia claimed that dataitem does not exist (so should be OK to create).

I'm making a release that will give me more information from the server response so I can figure out what I should do. It should be available in the next hour or so.
