Return, object property “undefined” “Cannot GET /src/html/undefined” on a Link

within the return statement there is a link element that has an object property as its value/href.
This link is wrapped around each item in my array. When the link is clicked “Cannot GET /src/html/undefined”

   const displayMovies = (Movies) => {
    const htmlString = Movies
        .map((item) => {
            return `
            <div class="Media-Card">
                <a href='${item.page}'><img class='Poster' src="${item.poster}" ></img></a>
                <h1 class='Media-Card-Header'>${item.title}</h1>
            </div>
        `;
        })
        .join('');
    searchlist.innerHTML = htmlString;
};

Within my object class, I have declared and assigned a value for href.

   this.page = page;
