On this entry, I get the following exception:
[W8s79wpAADsAAFlsN8wAAACW] 2018-10-20 14:30:15: Errore irreversibile di tipo "BadMethodCallException"
And the same goes for every other entry I tried to open from enwiki's filter 56. I guess this may be the same as T187153, but I'm opening a separate task to be sure.
