동작을 시켜보니 에러가 발생하여
Landing/ subscription Page 에&nbsp;
<div id="hwpEditorBoardContent" class="hwp_editor_board_content" data-hjsonver="1.0" data-jsonlen="8666"></div>
return &lt;Col key={index} lg={6} md={8} xs={24}&gt; 를 추가 하면 없어 집니다.
<div style="color: #d4d4d4; background-color: #1e1e1e; font-family: Consolas, 'Courier New', monospace; font-size: 14px; line-height: 19px; white-space: pre;"></div>

계속 따라하면서 동작은 되지만&nbsp; 아래와 같은 warning 이 나오는 데요. 원인이 무엇인가요? 다른 강좌에서도 마찬 가지 였습니다.
