map 오류

Uncaught TypeError: Cannot read properties of undefined (reading 'map')

const makeSitterReviews = (reviews) => {
  const reviewsList = document.getElementById('sitterReviewList');
  reviewsList.innerHTML =
    reviews
      .map((review) => {
        return `<li class="reviews">
      <p>${review.rating}</p>
      <p>
        <span style="font-weight: bold">${review.email}</span>
      </p>
      <p class="review-content">${review.content}</p>
      <div class="review-btnFD">
        <p class="review-createdAt">
          ${review.updatedAt}
        </p>
      </div>
    </li>`;
      })
      .join('');
};

reviews && reviews.map하면 해결!
