Cannot read properties of undefined (reading 'onDidPaste')

[jcdarwin]

Description

After upgrading craftcms/ckeditor (3.0.0 => 3.8.3), I find that when I visit the settings page (either for an existing configuration, or for a new configuration), I don't see any toolbar items either in the top area (i.e. under "Drag toolbar items into the editor") or bottom area (the toolbar).

I notice that there is an error in the dev tools console:

jquery.js?v=1714800000:2 jQuery.Deferred exception: Cannot read properties of undefined (reading 'onDidPaste') TypeError: Cannot read properties of undefined (reading 'onDidPaste')

I can confirm that this error did not appear in the devtools console in the previously-installed version (3.0.0)

However, the toolbar in a ckeditor field in an entry looks OK.

Steps to reproduce

1. Upgrade to 3.8.3
2. Visit /admin/settings/ckeditor/new
3. See that there is no toolbar / toolbar icons showing, and the error mentioned above appears in the devtools console.

Hi, thanks for reaching out! I can replicate this problem, but the error I see is different. For me, the issue was resolved after I cleared the “Compiled templates” cache. Could you please try that and let me know if it solved the problem? (You can clear the caches via Control Panel > Utilities > Caches or via the command line.)

Thanks @i-just -- that worked perfectly -- closing this issue.
