Passing variable from ejs to js script

I am trying to pass a variable from ejs to JavaScript function but keep getting undefined in output. Here is the code. It is supposed to render a table with file names and clicking on each file name should later redirect to a page which would render the file in the browser but I can't proceed without passing the parameter to URL.

        <% if (files.length > 0) {%>

        <table class="table table-hovered">

            <thead class="thead-light">

                <tr>

                    <th scope="col">No</th>

                    <th scope="col">File</th>

                    <% files.forEach((file, index) => { %>

                <tr>

                    <th scope="row">

                        <%= index + 1 %>

                    </th>

                    <td>

                        <a onclick="func(file.fileName);">

                            <%= file.fileName %>

                        </a>

                    </td>

                </tr>

                <% }) %>

                </tbody>

        </table>

        <% } %>

    </div>

</div>

<script>

    function func(fileName) {

        window.location.href = "/thesis_view/" + fileName;

    }

</script>









getStudentUploadThesisPage: (req, res) => {

        const getFilesQuery = "SELECT fileName FROM supervision INNER JOIN thesis ON supervision.thesisId = thesis.id INNER JOIN thesis_details ON thesis_details.thesisId = thesis.Id INNER JOIN people ON supervision.teacherId = people.id INNER JOIN thesis_file ON thesis_details.id = thesis_file.thesis_detail_id WHERE supervision.studId = " + req.session.userId;

        db.query(getFilesQuery, (err, result) => {

            if (err) {

                return res.status(500).send(err);

            } else if (result.length >= 0) {

                res.render('student_upload_thesis', {

                    files: result

                });

            }

        });

    }
