я есть вспомогательная функция в моем компоненте. Когда яconsole.log(helperFunction()) это, я получаю это в консоли.

Когда я пытаюсь добавить вспомогательную функцию в поле ввода для ее значения. Я понял это.

Как я могу получить[[PromiseValue]] в моем входе?

  render() {
    console.log(getProjectName());
    return (
      <form ref={(input) => this.eventForm = input} onSubmit={(e) => this.createEvent(e)} className="slds-form">

Вспомогательная функция
