Conf.Language(114)

Error message

Conf.Language(114)

What it means

After ContainsMarker passes, RenameTag trims leading/trailing '/' and whitespace; if the result is empty it returns Conf.Language(114) = 'Tag cannot be empty'. This catches labels that are only markers, slashes, or spaces (e.g. '#', '/', ' ', '/#') which survived the marker check but hold no real content.

Solutions

1. Provide a non-empty label containing at least one non-marker, non-slash character.
2. Frontend: disable Rename when the trimmed field is empty.
3. If renaming to remove a tag, use the delete-tag flow instead of renaming to empty.

Example fix

// before: newLabel="/" -> error 114
// after: newLabel="work"

// Go caller
label := strings.TrimSpace(strings.TrimSuffix(strings.TrimPrefix(newLabel, "/"), "/"))
if label == "" {
    return errors.New("tag label cannot be empty")
}

// Go
func nonEmptyTagLabel(label string) bool {
    t := strings.TrimSpace(strings.TrimSuffix(strings.TrimPrefix(label, "/"), "/"))
    return t != ""
}

When it happens

Trigger: POST /api/tag/renameTag with newLabel that is empty, all whitespace, only '/' separators, or after marker stripping becomes empty. Typing only spaces or slashes in the rename field.

Common situations: User clears the rename field and submits. Label is just '/'. Label after removing a leading '#' leaves nothing. Programmatic rename with an uninitialized string.
