The error is:
fallback[locale].filter is not a function or its return value is not iterable

  let fallbackLocales = [];
  if (isArray(fallback)) {
    fallbackLocales = fallback;
  } else if (isObject(fallback)) {
    const targets = [...locales, "default"];
    for (const locale of targets) {
      if (fallback[locale]) {
        fallbackLocales = [...fallbackLocales, ...fallback[locale].filter(Boolean)];
      }
    }
  } else if (isString(fallback) && locales.every((locale) => locale !== fallback)) {
    fallbackLocales.push(fallback);
  }
  return fallbackLocales;
