[openstreetmap/openstreetmap-website] ActionView::Template::Error (undefined method `redacted?' for nil:NilClass) in app/views/browse/_relation_member.html.erb (#1988)

[Andy Allan]

The extracts provided by Geofabrik are not "referentially complete" - that is, they contain relations with references to members which are not included in the extract. For example, the relation that you mention (2220322) has way 398377196 as a member, but that way is not included in the extract.

The api and website code is not designed to cope with the database being in an inconsistent state - that's why you get the server error.

The way to fix this is to pre-prepare the extract to avoid having any referential integrity problems. I'm not sure off the top of my head if there's a script available for this - suggestions welcome!
