Error on spbooking

now the page "daily tour" does not open, the error is the following:
syntax error, unexpected '[', expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$'

I think the problem is here,
$mParams = $menu->['params'];

 Can you help me.
 Thanks

the code:

$this->setState('list.start', $app->input->get('limitstart', 0, 'uint'));
        $this->setState('filter.language', JLanguageMultilang::isEnabled());
        $menu = $app->getMenu()->getActive();
        var_dump($menu->params);
        if(isset($menu) && isset($menu->params)){
            $mParams = $menu->params;
        }
        $cParams = JComponentHelper::getParams('com_spbooking');
        $limit = $cParams->get('packages_limit', 6);

code execution

the original code works but when clicking on the submit button of the search component you get the following error

Trying to get property 'params' of non-object in C:\wamp64\www\travel_savadori1\components\com_spbooking\models\packages.php on line 22

Running his suggestion does not show the error but persists. In fact, now in the search form only the date is displayed and the first part with two other parameters are cut.
How can I value the parameter $ mParams = $ menu-> params; which turned out to be null after hitting the submit button

![]()I tried to change the php version with different versions but nothing .. I also cleared the cache but nothing. the problem is not solved. how can I get that parameter to be valued.
