Conf.Language(126) (localized empty-bookmark-name message)

Error message

Conf.Language(126) (localized empty-bookmark-name message)

What it means

A bookmark rename resolves to an empty name after trimming whitespace, which is not allowed because a bookmark must have a non-empty label. The localized empty-name message (Conf.Language(126)) is returned. Note the marker check runs before trimming, and the emptiness check runs after strings.TrimSpace, so a name of only spaces also lands here.

Solutions

1. Provide a non-empty new bookmark name.
2. To remove a bookmark, call the dedicated remove/delete bookmark API instead of renaming to empty.
3. Validate client-side: trim the input and require length > 0 before invoking the API.
4. Show Conf.Language(126) in the UI to prompt the user for a valid name.

Example fix

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

function isValidBookmarkName(name) { return typeof name === 'string' && name.trim().length > 0 }

When it happens

Trigger: Calling RenameBookmark with newBookmark == "" or a whitespace-only string (e.g. " "); the rename dialog submitted with a cleared input field.

Common situations: User deletes all text in the rename input and confirms; automation scripts pass an empty string to clear a bookmark instead of using the proper remove-bookmark API.
