Почему не работает верстка на React?

Пишу код для веб-чата.
Описал серверную часть, но не работает верстка на реакте.
Суть такая - мне нужно ввести имя, и скопировать id конференции(с этим и проблема, id не копируется). Скинуть id другу и он подключается к конференции.
Не работает процесс извлечения id, и звонка другому пользователю
