<div style="font-family: 'Malgun Gothic';">There was an unexpected error (type=Internal Server Error, status=500).</div>

<pre style="background-color: #2b2b2b; color: #a9b7c6; font-family: 'JetBrains Mono',monospace; font-size: 12.0pt;">spring.datasource.username=sa </pre>
이부분을 추가해줬더니 오류가 해결이 되었습니다!!!
