我尝试通过从复选框中选择用户并为每个用户输入不同的点来插入数据，但提交时出现此错误

这是插入多个值的正确方法，这些值来自模型中的复选框，每个用户都有不同的点
有人能帮我找出我错在哪里吗？

<form method="post" action="{{route('user.action.push')}}" >

                <table  class="display table table-bordered table-separated" >

操作用户推送函数

public function ActionUserPush(Request $request){
            
       foreach($request->user_id as $user_id){
                $point = $request->point_[$user_id];
    
               ActionUser::insert([
                  
                    'user_id'=>$user_id,
                    'point' =>$point,
                    'action_id'=>$request->action_id,
    
                ]); }
    
            $notification = array(
                'message' => ' Action Activited Successfully',
                'alert-type' => 'success'
            );
            return redirect()->route('user_action_view')->with($notification);}
