The background on this PR is that we are not actually emitting an error, only the retry count.

KFC

  this.#events.emit(WatchEvent.RECONNECT, this.#retryCount);

Pepr

  // in this context, err is the retryCount and retryCount is always going to be undefined
  watcher.events.on(WatchEvent.RECONNECT, (err, retryCount) =>
    logEvent(WatchEvent.RECONNECT, err ? `Reconnecting after ${retryCount} attempts` : ""),
  );
