select value is not selected for select input

[desaiuditd]

For the following code, I'm not able to get the selected=selected attribute for the valid <option> tag in select input of the form.

Can someone help me?

const formAttr = {
    method: 'POST',
    action: '/api/admin/model/client/'
};
const formData = {
    'user': '59fae7403de42b36749a9c82'
};
const form = Form.create(formAttr, formData);
const users = {
    '58cd87da1b2d7d1e4563e1ca': '[email protected]',
    '59fae7403de42b36749a9c82': '[email protected]'
}

form.select()
    .attr({
        name: 'user',
        class: 'form-control',
    })
    .setOptions(users)
    .setEmpty('Select User')
    .render();

Output

<select name="user" class="form-control">
    <option value>Select User</option>
    <option value="58cd87da1b2d7d1e4563e1ca">undefined</option>
    <option value="59fae7403de42b36749a9c82">[email protected]</option>
</select>
