production.ERROR: Exception: DateTime :: __ construct (): не удалось проанализировать строку времени (3) в позиции 0 (3): неожиданный символ в Laravel

Question

Я работаю над Dynami c Форма ввода в Laravel -5,8:

public function store(StoreGoalRequest $request)
{
        $goal = new Goal();
        $goal->goal_type_id             = $request->goal_type_id;

    $goal->save();        
    foreach(Arr::wrap($request->activity) as $key => $activity){
            $startDate = Carbon::parse($request->start_date[$key]);
            $endDate = Carbon::parse($request->end_date[$key]);

            $goaldetail = new GoalDetail();
    $goaldetail->activity                   = $request->activity[$key];
            $goaldetail->start_date                 = $startDate->toDateString();
             $goaldetail->end_date                   = $endDate->toDateString();                 
             $goaldetail->save();

         }
}

Правила

        'start_date.*' => [
            'required', 
            'date',
            'date_format:d-m-Y',
        ],
      
        'end_date.*' => [
            'required', 
            'date',
            'date_format:d-m-Y',
            'after:start_date.*'
        ],        

модель

protected $dates = [
    'start_date',
    'end_date'
    ];
