dropboxjs longpoll : error 400 : You must issue the request to "notify.dropboxapi.com"

Hi,

When I'm calling the filesListFolderLongpoll() method I get the following error:

status: 400,
 text: 'Incorrect host for API function "files/list_folder/longpoll". You must issue the request to "notify.dropboxapi.com".'

I'm getting a cursor with filesListFolderGetLatestCursor() and then I give the cursor I just retrieved to filesListFolderLongpoll().

Here is a sample code:

var Dropbox = require('dropbox');
var dbx = new Dropbox({accessToken: 'MY_ACCESS_TOKEN_HERE'});
dbx.filesListFolderGetLatestCursor({path: '',
        recursive: false,
        include_media_info: false,
        include_deleted: false,
        include_has_explicit_shared_members: false
    })
    .then((last_cursor) => {
        dropboxLongpoll(last_cursor.cursor);
    })
    .catch((err) => {
        console.log(error);
    });

function dropboxLongpoll(last_cursor) {
    dbx.filesListFolderLongpoll({cursor: last_cursor, timeout: 30})
        .then((result) => {
            console.log(result);
            
            // [ ... do stuff ...]
        })
        .catch((err) => {
            console.log(err);
        });
}

I'm using Dropbox javascript SDK in version 2.3.0.

Did I make any mistakes ?

Thank you!
