Special:EditWatchlist/raw gives Exception encountered, of type "Wikimedia\Assert\ParameterTypeException"
Closed, ResolvedPublic

Description

At certain wikis, I get this error message when trying to access [[Special:EditWatchlist/raw]]
Exception encountered, of type "Wikimedia\Assert\ParameterTypeException"
E.g.
https://commons.wikimedia.org/wiki/Special:EditWatchlist/raw
https://www.mediawiki.org/wiki/Special:EditWatchlist/raw
https://meta.wikimedia.org/wiki/Special:EditWatchlist/raw
https://pt.wikibooks.org/wiki/Special:EditWatchlist/raw

It seems to be restricted to 1.27.0-wmf.18 for wikis that use Flow, and it is dependent on the account having a Flow topic on their watchlist.
I.e. as of today it does not affect
https://en.wikipedia.org/wiki/Special:EditWatchlist/raw
https://en.wikiquote.org/wiki/Special:EditWatchlist/raw (Flow not used here)
https://fr.wikibooks.org/wiki/Special:EditWatchlist/raw (Flow not used here)
and does not affect a vanilla test account at Commons until I watchlist a topic, e.g. https://commons.wikimedia.org/wiki/Topic:Smtrcre7hhh81d4z

9:26 PM <addshore> Either $watchedItem->getLinkTarget()->getNamespace() returns a non int on line 319 in SpecialEditWatchlist
9:26 PM <addshore> Or from the use of namespace from the db on line 363
9:26 PM <addshore> probably the second one

Might be worth casting all the stringyness to ints.
TBH it would be worth doing this throughout core....

When reviewing all constructions of TitleValue in recently added code I also came accross this one
https://gerrit.wikimedia.org/r/#/c/279334/
Which may has resulted in a similar situation.

I guess this is why special page tests etc would be nice..

Checked Special:EditWatchlist/raw on all listed wikis - seem to be ok. Also, added a Flow topic to my watchlist in commons.wikimedia.org to see if the raw watchlist is broken - no errors displayed.
