    save_history: false,
    caching: false,
    data: {
      is_ajax: true,
      features_hash: generateHash(container),
      security_hash: s_hash
    },
    scroll: '#my_id',
    obj: obj,
    security_hash: s_hash,
    callback: _getDataRespons
    };
    if (ajax_ids) {
       $.ceAjax('request', url, params);

Try to change your code to something simple, like


{$smarty.const.TIME}

and check the result

I get 1575641422.

So request is correct. Possibly the reason in the response. Try to add custom code line by line to find a reason
