Production Error: mw.msg(...).escaped is not a function
Closed, ResolvedPublicPRODUCTION ERROR


Steps to replicate the issue :

What happens?:

Uncaught TypeError: mw.msg(...).escaped is not a function
  at child.formatMetadata (<anonymous>:114:46)
  at child.trigger (<anonymous>:715:695)
  at child.change (<anonymous>:720:801)
  at child.set (<anonymous>:717:927)
  at success (load.php?lang=en&modules=ext.pageTriage.views.toolbar&skin=vector&version=io7sr:5:730)

  at XMLHttpRequest.<anonymous> (load.php?lang=en&modules=ext.centralNotice.choiceData|jquery%2Coojs-ui-core|jquery.ui&skin=vector&version=kwgi0:142:444)

Clicking the "Mark" button (tick mark) throws up another error

Uncaught ReferenceError: noteTarget is not defined

which i assume is related to the first.

What should have happened instead?: No errors should have occurred and the mark flyout should have opened

I am also getting JavaScript errors on that page.

First visit

On first visit, I get this different error:

Chrome, Windows, vector, Page Curation toolbar cookie set to not hidden or minimized

It is coming from modules/ext.pageTriage.views.toolbar/ToolbarView.js line 7

const article = new mw.pageTriage.Article( {
	eventBus: eventBus,
	pageId: mw.config.get( 'wgArticleId' ),
	includeHistory: true
} );

Second and subsequent visits

On refresh (tried multiple times), I am getting the OP's error "Uncaught TypeError: mw.msg(...).escaped is not a function" error.

Page Curation toolbar not showing this article as reviewed

This article is reviewed according to the pagetriagelist API, but it is not showing as reviewed in the Page Curation toolbar.

Assuming you'll want to backport this?

It's a really rare bug. It's been in production since 2018. Probably OK to skip backport unless you have the free time for it.
