ПРОБЛЕМА
Я меняю компоненты на основе состояния в компоненте Dashboard (родительский) и передаю реквизиты всем им. Когда я вхожу с помощью оптовика, приложение работает без проблем, но когда я вхожу с учетной записью продавца, приложение возвращает
TypeError: this.props.handleClick не является функцией
когда я нажимаю на button-handleClick () -> переключаю компоненты через handleClick, который меняет состояние
Мои компоненты почти идентичны, и я понятия не имею, откуда это.
Спасибо Вы заранее! :)
