코드 밑에 실행을 확인해보니

werkzeug.exceptions.BadRequestKeyError: 400 Bad Request: The browser (or proxy) sent a request that this server could not understand.

KeyError: 'url_give'

ketError라 뜨는데 제가 명령어를 잘못 입력한건가요?

function posting() {
    let url = $('#url').val()
    let star = $('#star').val()
    let comment = $('#commet').val()

    $.ajax({
        type: 'POST',
        url: '/movie',
        data: {url_give:url, star_give:star,comment_give:comment},
        success: function (response) {
            alert(response['msg'])
            window.location.reload()
        }
    });
}

        data: {url_give:url, star_give:star,comment_give:comment}, 여기 url_give, star_give, comment_give가 보라색 글씨가 아닌데 잘못된건가요?
