Bug: this-month default filter results in HTTP 400 'bad request'

When I click on one of the helpful links in w:WP:Backlog I get directed to a page like this (putting raw URL for clarity):

https://pageviews.wmcloud.org/massviews/?platform=all-access&agent=user&source=category&target=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FCategory%3AAll_self-contradictory_articles&range=this-month&subjectpage=1&subcategories=1&sort=views&direction=1&view=list

Note how the "range" parameter is the string "this-month".
The page decides that this-month means a date range that starts January 1st, 2026 and ends on 31st December, 2025.
This results in API requests that the server understands is incorrect, because, as the server says in its HTTP 400 responses (visible in the browser dev console): "start timestamp should be before the end timestamp".

In the user-visible side of the browser, this is the error message:
"Error querying Pageviews API - Bad Request" (next to each result entry)
"Building dataset..." (the progress bar just stays on that).

To initiate a new request, I can remove the 'processing' class from the 'main' HTML element in my dev console, but other than this, it doesn't seem possible to cancel an ongoing request initiated this way without navigating away from the page. So an additional bug may exist where the "processing" class is not properly removed from '<main>' when a query should have errored out.

I use Firefox 146.0.1 on Linux. Komonzia (talk) 19:23, 1 January 2026 (UTC)

Looks like "this month" always refers to the calendar month - in which case this bug (if it still exists) only occurs on the 1st of every month. I suppose it can be easily scripted away by ensuring any requests that go to the API have the 'earlier' date as the 'from' date and the 'later' date as the other one, in the filter.

@MusikAnimal (WMF): I'm not sure if this is monitored Komonzia (talk) 16:11, 24 January 2026 (UTC)

@Komonzia Sorry for the late reply! I was on sabbatical and just got back into the office today. This is indeed a bug. I think part of the issue is that we're converting to UTC sometimes, other times not. That is a known bug that's been around for quite a while. I'll try to look into it soon.

Feb 8, 2026 - Not showing numbers for views of any page

The numbers are not showing, when i clicked on top page for daily, it shows this - Error querying Pageviews API - Not Found. ~2026-87818-0 (talk) 11:39, 9 February 2026 (UTC)

also happened on Feb 12, 2026. Sinsyuan (talk) 06:48, 13 February 2026 (UTC)

This just means the upstream pageviews pipeline was delayed, for whatever reason. The Data Engineering team is usually notified about it one way or another and it gets resolved in due time. Per their intake process, I recommend creating a Phabricator task if you see the data is over more than one day behind. If you're checking the day-of, it could be only a matter of hours before the data shows up, so a Phab ticket may not change anything if the issue is simply things are running slow. Hope this helps, MusikAnimal (WMF) (talk) 03:12, 3 March 2026 (UTC)

Hi all - I'm looking through some pageview pipeline errors and re-running some jobs to see that we can get this data caught up. ABaso (WMF) (talk) 18:22, 3 March 2026 (UTC)

Let me withdraw that statement and say if you think things are at all delayed, go ahead and file a task as described at mw:Data Platform Engineering/Intake Process. Or message here and I'll forward the issue to Data Engineering. I was on sabbatical which is why these reports were not noticed when they were made last month. Anyway, there is a similar issue happening right now and it's being looked into. Best, MusikAnimal (WMF) (talk) 18:22, 3 March 2026 (UTC)

I apologize, I was responding about some data unavailability from the last few days, not stuff from back in February. Looking back at the data from February 8 and February 12 for a couple of articles (Cat and Dog) I see pageview data are showing up in the tool now for those days.

However, it is true that presently I'm working toward getting some data files produced from the last couple of days where data jobs stalled out. Apologies for any inconvenience!

@MusikAnimal (WMF) is right, if things are delayed, please do feel free to file a Phabricator task. Task triage and monitoring of these data pipelines occurs throughout the workweek, so tasks filed on the weekend may take a few days to get a look. I'm sorry there was a delay here on-wiki. Thank you @MusikAnimal (WMF) for flagging this. ABaso (WMF) (talk) 21:42, 3 March 2026 (UTC)

The visitor counter is not working in March.

Pageviews not working in March Lovepeacejoy404 (talk) 03:49, 3 March 2026 (UTC)

See the thread above. This time, it looks like it was an actual issue that Data Engineering was not aware of! They are now, though, and are looking into it. Thanks for reporting! MusikAnimal (WMF) (talk) 18:20, 3 March 2026 (UTC)

@Lovepeacejoy404, @MusikAnimal (WMF) how is it looking now? Non-Euclidean geometry looks to have pageview data in its corresponding pageviews.wmcloud.org representation now, for example.

@MusikAnimal (WMF) I forget whether pageviews.wmcloud.org may have some caching on it whereby a lookup for pageviews for an article (e.g., Cat) for a day where pageviews data haven't yet materialized may show a cached response, such that a subsequent request for the page could show no data for a while, for example. Although to be clear some data jobs needed to be caught up due to processing backlogs. ABaso (WMF) (talk) 04:18, 4 March 2026 (UTC)

It works now. Thanks. Lovepeacejoy404 (talk) 05:01, 4 March 2026 (UTC)

Change example for wikilinks

If you go to https://pageviews.wmcloud.org/massviews/ and select "wikilinks", the placeholder is https://en.wikipedia.org/wiki/Book:New_York_City. Since the book namespace was deleted from enwiki years ago the placeholder should be changed to something else. * Pppery * _{it has begun} 04:59, 24 October 2024 (UTC)

I'll get this changed as ell, thank you for re-posting. MusikAnimal (WMF) (talk) 18:38, 16 March 2026 (UTC)

This can be considered Done. Not deployed, but it's fixed and will go out with the next release. MusikAnimal (WMF) (talk) 19:03, 16 March 2026 (UTC)

I should have this and the issue above with Massviews fixed sometime in the next 4-5 hours. MusikAnimal (WMF) (talk) 21:40, 14 March 2026 (UTC)

Anddddd my time is up :P Your issue, specifically, I have fixed. It'd be easier to deploy in tandem with #Massviews not returning any results so that is the current hold up. Regardless, I'll get the edit counter back to normal sometime tomorrow. Thanks for your patience, MusikAnimal (WMF) (talk) 03:05, 15 March 2026 (UTC)

Done This should be fixed now. MusikAnimal (WMF) (talk) 00:23, 17 March 2026 (UTC)

Redirect views not shown on pageviews analysis even when "Include redirects" is ticked

The issue occurs both on Windows and Android at least when using chrome. To pick an obvious example, the "Redirect Views" page for Stephanorhinus kirchbergensis shows that it got 1,446 views from 15 February to the 16 of March, of which 809 were non-redirect views. [1], when checking the pageviews analysis for the same article and time period, it only shows the 809 number including when the "Include redirects" box is ticked [2] Hemiauchenia (talk) 21:01, 17 March 2026 (UTC)

Ah, yes. I'm not sure what to do about this one… we could potentially be firing off a lot of requests. I'll get it fixed, but you'll have to okay with waiting a bit longer to get results than you did in the past. Thanks for letting me know, MusikAnimal (WMF) (talk) 21:40, 17 March 2026 (UTC)

Missing data for some days

Hi, i discovered that there is no data for the following dates:

https://wikimedia.org/api/rest_v1/metrics/pageviews/top/it.wikipedia/all-access/2015/06/29

https://wikimedia.org/api/rest_v1/metrics/pageviews/top/it.wikipedia/all-access/2024/03/31

is this a bug of pageview API, or is the data actually missing? Sette-quattro (talk) 13:22, 23 March 2026 (UTC)

can we use Massviews with another language

hi :) The tool is looking for page in the en wiki. Is it possible to use another wiki language ? Thanks :) Haymillefolium (talk) 00:00, 25 March 2026 (UTC)

I got my response : we can set the language in the page pile. It found a lot of page in another language (the pile was en and the page where fr) don't get why Haymillefolium (talk) 00:03, 25 March 2026 (UTC)
