Quote Callouts

Customization Theme component

I have the following error, only when using the de translation*:

JS-Console:

It occurs in the last line of this quote:

class QuoteCallouts {
  constructor(owner, api) {
    [...]
    window.I18n.translations[
      window.I18n.fallbackLocale || "en"
    ].js.composer.callout_sample = ``;
  • Set /u//preferences/interface “Interface language” to “German (Deutsch)”

The error seems to have been introduced in one of the last Discourse updates between 2026.3.0-latest and 2026.4.0-latest, but I can’t pinpoint it any further. Currently I’m at 2026.4.0-latest 4b2c45376d and Quote Callout v0.0.1 9aa6548
