Conf.Language(126)

Error message

Conf.Language(126)

What it means

RenameBookmark rejects an empty new bookmark name with a localized 'empty name' error (language key 126). After trimming surrounding whitespace, a name that is empty or whitespace-only cannot identify a bookmark group, so the operation is refused.

Solutions

1. Provide a non-empty, non-whitespace new name
2. Guard the call site: skip or abort the rename when strings.TrimSpace(newName) == ""
3. In UI, disable the confirm button until trimmed input is non-empty

Example fix

// before
if err := model.RenameBookmark(old, name); err != nil { return err }
// after
name = strings.TrimSpace(name)
if name == "" { return errors.New("bookmark name required") }
if err := model.RenameBookmark(old, name); err != nil { return err }

if strings.TrimSpace(newName) == "" { return errors.New("bookmark name required") }

if err := model.RenameBookmark(old, name); err != nil {
  // show message; e.g. language key 126 localized text
}

When it happens

Trigger: Calling RenameBookmark with newBookmark = "" or only spaces/tabs (e.g. user cleared the rename dialog field and confirmed).

Common situations: UI dialogs that don't disable the OK button on empty input; scripts passing an unset variable as the new name.
