Невозможно получить доступ к новому заданному значению из области ipcRenderer - электрон javascript

Question

Я пытаюсь обновить значение переменной в моем вызове ipcRenderer.on ('Отправка профиля назад', функция (..) ..), но моя переменная не обновляется до нового значения, когда я вызываю его за пределами сфера В моей консоли я получаю неопределенное значение для переменной profileChosen, но внутри функции ipcRenderer я получаю правильные значения profileChosen. profileChosen - это класс Profile.
