Description

Error code

62ebd064-6f77-46c5-9851-68c9cf93282a

Steps to replicate the issue (include links if applicable):

Try to review https://ru.wikipedia.org/w/index.php?title=Ковальчук,_Елена&redirect=no
Get an Internal Server Error

What happens? (interface review):
If you click on "Accept Revision" button, browser would make a POST request to https://ru.wikipedia.org/w/rest.php/flaggedrevs/internal/review/Ковальчук,_Елена and get the following HTTP500 response:

{"message":"Error: exception of type UnexpectedValueException","httpCode":500,"httpReason":"Internal Server Error"}

What happens? (API review):
If you'll try to review the page with API by making a request to https://ru.wikipedia.org/w/api.php?action=review&format=json&revid=118792362 , it would fail as well. Pywikibot throws the following exception:

pywikibot.exceptions.APIMWError: internal_api_error_UnexpectedValueException: [62ebd064-6f77-46c5-9851-68c9cf93282a] Caught exception of type UnexpectedValueException
[errorclass: UnexpectedValueException;
 servedby: mw-api-ext.eqiad.main-78789c78f5-dnx47]

Other information:
This page was deleted and later restored, and that might've broken FlaggedRevs.

Event Timeline

Facenapalm created this task.Jul 1 2024, 8:00 AM

I tested the "delete then undelete" hypothesis on localhost and was unable to reproduce. So the steps to reproduce are probably different / more complicated.

Step to reproduce I tried:

add ruwiki config to LocalSettings.php
as a logged out user, create a page in mainspace
log in as sysop
add self to the 'editor' group
delete the page
undelete the page
review the page (it worked)

Novem_Linguae added a project: Wikimedia-production-error.Jul 1 2024, 8:41 AM

Novem_Linguae updated the task description. (Show Details)

The page mentioned in the description is a redirect, did you try that? I can imagine that something automatically resolves the redirect, leading to a mismatch in the page ID. (Or something automatically resolved the redirect and wrote that into the database in the past two and a half years.)

Krinkle added a project: Unstewarded-production-error.Jul 25 2024, 3:20 PM

Krinkle moved this task from Untriaged to Jul 2024 on the Wikimedia-production-error board.

This could be same. Page was moved and after that it could not be reviewed any more. One exception though when i clicked enough i was able to get old revision reviewed. However, I was not able to review latest versions. Page was this

https://fi.wikipedia.org/wiki/Sveitsin_Superliiga

And request and server answer was this

Also, workaround was that user did edit to the page so that the last version was not anymore the log event and was able to review the page.
