Error
MediaWiki version: 1.36.0-wmf.5
message
Return value of Wikimedia\Parsoid\Wt2Html\PP\Processors\WrapSections::getDSR() must be of the type integer, null returned
Impact
12 logstash events in the last 5 minutes. Top of logspam-watch. User impact not yet clear.
Notes
The request URL does not match any known (REST API) handler when I open it manually. I’m not sure if it’s correct.
All occurrences in Logstash are for the same URL, though.
Same error message as T236912 (resolved eight months ago).
