Why is there an error in JSX code?

Question

JavaScript

Why might an error occur here?

<div className={classed.wrap}>
      <NavLink to="/test" className={classed.purple}>
        <h5>рейтинг</h5>
        <h4>Класса</h4>
        <div className={classed.ic}>
          <img src="#" alt="Rating one" />
        </div>
      </NavLink>
</div>

Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
