On the Beta Cluster, I get this error when accessing the page information for any file (regardless of whether it has structured data or not):

I can’t find any occurrences of this error in Beta Logstash, not even my own error pasted above (presumably due to T233134: logstash-beta.wmflabs.org does not receive any mediawiki events), so I don’t know how new this error is.
