I cloned and added all configurations for PageTriage in the LocalSettings file. After that, I ran docker-compose exec mediawiki composer update and docker-compose exec mediawiki php maintenance/update.php. I created several new pages as an anonymous and logged-in user. They all appear in RecentChanges but none appear in Special:NewPagesFeed.

Might check on the database to see if there are any entries in the database tables.

I see the tables in the database, but no information in them except for pagetriage_tags.

Comparing some Ajax requests between my local environment and en.wiki, I see that my local environment throws some warnings about unrecognized parameters and the date format is different. This might be the reason articles are not showing. I'll take a look at how dates are stored in articles to see if there is something there.

I see that a Add to the New Pages Feed link has been added to the page toolbar on the right of my screen. I press it and it returns a success message. However, I still don't see the articles in Special:NewPagesFeed and there are no entries in the database.

@kostajh Have you had this issue where no new pages are showing up in Special:NewPagesFeed in your local environment?

I have not. I think the easiest way to figure out what is going on is to use XDebug and set a breakpoint in extensions/PageTriage/includes/Hooks.php#onPageSaveComplete, then follow what's happening.

What does $wgPageTriageNamespaces look like in shell.php?

What does $wgPageTriageNamespaces look like in shell.php?

It's

$wgPageTriageNamespaces
= [
    0,
  ]

which I assume is NS_MAIN

After following @kostajh's advice to use MySQL instead of SQLite, I found the error that keeps data from being inserted into the pagetriage_page table:

Error: stepping, NOT NULL constraint failed: pagetriage_page.ptrp_tags_updated (19).

Will look further into it.

I filed T333389 to follow up on the SQLite error. A patch has been created that fixed it. With those changes, my local environment works so I will now move this task to Done.
