cakephp4 get 1st record from containing table with order by a field - orm

Question

I have cakephp4 project
having 1 to many relationship between Portfolios and PSnaps
I want to show all 'Portfolios' with one associated record from PSnaps where its PSnaps.status=1 and order=>['PSnap.order_at'=>'ASC']
I tried many things but getting the correct result
below is giving 90% correct result only ordering on PSnaps.order_at is not working.
along with hasmany() i have created hasOne() association as shown in below model
Model
class PortfoliosTable extends Table
{
public function initialize(array $config): void
{
parent::initialize($config);
$this->setTable('portfolios');
$this->setDisplayField('id');
$this->setPrimaryKey('id');
$this->hasOne('FirstPSnaps', [
'className' => 'PSnaps',
'foreignKey' => 'portfolio_id',
'strategy' => 'select',//also tried join
//'joinType'=>'LEFT',//also tried inner,left,right
//'sort' => ['FirstPSnaps.order_at' => 'ASC'], //*******this is not working
'conditions' => function (\Cake\Database\Expression\QueryExpression $exp, \Cake\ORM\Query $query) {
$query->order(['FirstPSnaps.order_at' => 'ASC']);//*******also not working
return [];
}
])
;
$this->hasMany('PSnaps', [
'foreignKey' => 'portfolio_id',
]);
}
Controller
$pfolios = $this->Portfolios->find('all')
->select(['Portfolios.id','Portfolios.client','Portfolios.country','Portfolios.url'])
->where(['Portfolios.status'=>1])
->order(['Portfolios.order_at'=>'asc','Portfolios.id'=>'asc'])
->limit(8)
->contain([
'FirstPSnaps'=>function($q){
return $q
->select(['FirstPSnaps.portfolio_id','FirstPSnaps.snap'])
//->where(['FirstPSnaps.status'=>1])
//->order(['FirstPSnaps.order_at'=>'asc'])
;
}
])
->toArray();
it is returning correct porfolios with 1 p_snap record but ordering/sorting is not correct as I need first p_snap something like where p_snap.status=1 and p_span.portfolio_id= portfolios.id limit 1.
