pagination with join and array in cakephp

Hi, in cakephp I used a 'find all' to do a complex and this works fine as below. My issue is I am trying to convert this to a set  paginated results and I keep getting offset warning Illegal offset type [CORE\Cake\Model\Model.php, line 2936.
I am sure the issue is simple but is there a way to to do this with the $option arrays I have for the search . I didnt see an example in the docs for the paginate results with an array set for the options
