Question

Я создаю ссылки на категории модуля FAQ.Есть проблема.Вот мой код и отчет об ошибках выше этого.

        <ul>
    {
      this.props.categories.map((category) => {
        return (
          <li className="text-white d-inline-block w-100 clearfix ml-0" key={ category.id }>{ category.name }
             <a className="btn btn-primary float-right" onClick={ () => {
               this.handleEditOpenModal(category.id);
             } }>Edit</a>
             <NavLink to={'/' + category.id } className="btn btn-warning float-right">Add To</NavLink>
             <a className="btn btn-danger float-right"> Delete </a>
           </li>
        );
      })
    }
    </ul>

Consider adding an error boundary to your tree to customize error handling behavior.

Как я понимаю, проблема близка к строке

                 <NavLink to={'/' + category.id } className="btn btn-warning float-right">Add To</NavLink>

Если я не генерирую адрес (например, <NavLink to="/5ecf1cc7-e343-4ce9-bf71-26e02efeb7ba">...), в этом случае у меня нет проблем, но это не то, что мне нужно.

Что вы думаете?Thanx
