We get this crash on production for our websites.

Uncaught TypeError: Cannot read properties of undefined (reading 'replace')

Here is our ckeditor settings

CKEDITOR_SETTINGS = {
    "language": "{{ language }}",
    "toolbar": "CMS",
    "toolbar_CMS": [
        ["Undo", "Redo"],
        ["cmsplugins", "cmswidget", "-", "ShowBlocks"],
        ["Format", "Styles"],
        ["Link", "Unlink", "Anchor"],
        ["Maximize", ""],
        "/",
        [
            "Bold",
            "Italic",
            "Underline",
            "-",
            "Subscript",
            "Superscript",
            "-",
            "RemoveFormat",
        ],
        ["JustifyLeft", "JustifyCenter", "JustifyRight", "JustifyBlock"],
        ["HorizontalRule"],
        ["NumberedList", "BulletedList", "-", "Outdent", "Indent", "-", "Table"],
        ["Source"],
     ]
}       

I think it might have to do with the language settings and some people have not got this error if they don't have this setting.
