list 검색기능 만드는 중에 detail.ejs 에러가 나옵니다

<div class="container input-group mb-2">
<input class="form-control" id="search-input">
<button class="input-group-append btn btn-danger" id="search">검색</button>
</div>

<script>
$('#search').click(function(){
var 입력한값 = $('#search-input').val()
window.location.replace('/search?value=' + 입력한값)
})
</script>

list.ejs에서 해당코드 작성후 검색버튼을 누르면

이런 에러가 발생합니다

detail.ejs 해당부분 코드

<div class="container mt-4">
<h4 class="text-center">상세 페이지</h4>

<div class="card" style="width: 100%">
<div class="card-body">
<h5 class="card-title">제목: <%= data.제목 %></h5>
<h6 class="card-subtitle mb-2 text-muted">날짜: <%= data.날짜 %></h6>
<p class="card-text">
Some quick example text to build on the card title and make up the
bulk of the card's content.
</p>
<a href="/edit/data._id" class="card-link">수정하기</a>
</div>
</div>
</div>

server.js /detail get요청코드

app.get("/detail/:id", function (요청, 응답) {
db.collection("post").findOne(
{ _id: parseInt(요청.params.id) },
function (에러, 결과) {
console.log(결과);
응답.render("detail.ejs", { data: 결과 });
}
);
});

list.ejs 에 검색기능을 추가한후 검색버튼을 누르면 detail 페이지로 이동하는것도 아닌데

왜 갑자기 detail.ejs 에서 에러가 발생하는걸까요 ? ?
