Error: 500, Internal Server Error on many Commons categories.
Closed, DuplicatePublic

Description

Many category pages like https://commons.wikimedia.org/wiki/Category:Art_in_Norway and https://commons.wikimedia.org/w/index.php?title=Template:Countries_of_Europe&oldid=209196338 trigger 500 errors with normal viewing and when trying to open in API.

Probably LUA related because a lot of these pages are in https://commons.wikimedia.org/wiki/Category:Pages_with_script_errors .

Example:

Request from 2001:<etc> via cp3031 cp3031, Varnish XID 823167598

hhvm error logs have "Fatal error: unknown exception"

could this be similar to T70196 ?

@zhuyifei1999 you closed this on as a duplicate, but the other bug is scoped to non-English. You might want to update that one if the scope has gotten bigger.
