This problem appears to be caused when a custom filter which does not exist in the database is applied as the default filter, but it's not known how that happens. The problem can usually be fixed by adding query/cXWUBtEYlPCo/ to the end of the board's URL (e.g. https://phabricator.wikimedia.org/project/board/483/query/cXWUBtEYlPCo/ for the VisualEditor board) and changing the default filter back to something else.

I was hoping this was a transient issue, but it's been going on for hours now and it's preventing the team from doing their work, so I'm escalating the priority.

https://phabricator.wikimedia.org/project/board/483/manage/ shows it's enabled... let's try disabling and re-enabling to see if that helps things?

hm nope, https://phabricator.wikimedia.org/project/board/483/disable/ gives a 404 when you press the button (this shows in the JS console)

You can still view the list of tasks using task search: https://phabricator.wikimedia.org/maniphest/query/9WFEhfANhE6N/#R (note that it is paginated).

(Frankly, it seems more useful without the arbitrary columns…)

I fiddled a bit, tried reverting the sprint change earlier, no luck: https://phabricator.wikimedia.org/project/manage/483/#47174

Same here. No luck.

Somehow a custom filter was applied but it didn't exist in the database, causing a 404. I'm going to look into changing the behavior when the filter cannot be found. A 404 isn't very helpful.

For reference, what was done was to go to https://phabricator.wikimedia.org/project/board/483/query/cXWUBtEYlPCo/ (that ID on the end can be reused on other projects it seems), set the filter to open tasks and then save that as the default filter.

Aklapper renamed this task from 404 on VisualEditor workboard to 404 on VisualEditor workboard (due to custom filter applied which did not exist in database).Jul 10 2018, 8:19 PM

Great. Thanks everyone!

This fixed it again, but would be interesting to know why this keeps happening.

Indeed, I have no idea how/why this occurs.

@mmodell: This should show if someone changed the default filter view after 20180701 on one these two boards:

SELECT objectPHID, authorPHID, oldValue, newValue FROM project_transaction WHERE (objectPHID = "PHID-PROJ-zzvpaq4lhxoz4fx2ymwj" OR objectPHID = "PHID-PROJ-dafezmpv6huxg3taml24") AND transactionType = "project:filter" AND dateModified > 1530396000;

After a few weeks with no issues, this has happened three times in the past 48 hours on the VisualEditor workboard. It's not causing any seriously blocking issues at present because the workaround documented in the task description still works, but it is quite annoying.

This happened again on the VisualEditor workboard last Wednesday 5th September, during a sprint planning meeting.

This happened again for readers-web-backlog but the fix suggested worked.

https://discourse.phabricator-community.org/t/workboard-404-after-using-view-as-query/1954 might be potentially related?

I did that ^ for User-Jdlrobson, should be fixed now.
