Laravel Filament 提示： No property found for validation 错误的解决办法

如题，Laravel Filament 自定义页面中包含表单，提交时报错：No property found for validation。

错误代码如下：

<?php

namespace AppFilamentManagementPages;

use AppSettingsBedroomSettings as Settings;
use FilamentFormsComponentsDateTimePicker;
use FilamentFormsComponentsTextInput;
use FilamentFormsConcernsInteractsWithForms;
use FilamentFormsContractsHasForms;
use FilamentFormsForm;
use FilamentFormsGet;
use FilamentNotificationsNotification;
use FilamentPagesPage;

class BedroomSettings extends Page implements HasForms
{
    use InteractsWithForms;
    
    protected static ?string $navigationIcon = 'heroicon-o-document-text';
    protected static ?string $navigationLabel = '设置';
    protected static ?string $title = '设置';
    protected static string $view = 'filament.management.pages.bedroom-settings';

    public function form(Form $form): Form
    {
        return $form
            ->schema([
                TextInput::make('number')
                    ->label(__('settings.bedroom.number'))
                    ->required()
                    ->live(),
                TextInput::make('price')
                    ->label(__('settings.bedroom.price'))
                    ->required()
                    ->live(),
                DateTimePicker::make('open_time')
                    ->label(__('settings.bedroom.open_time'))
                    ->required()
                    ->live(),
                DateTimePicker::make('close_time')
                    ->label(__('settings.bedroom.close_time'))
                    ->required()
                    ->live()
            ])
            ->columns(2)
            ->statePath('data');
    }

    public function mount(): void
    {
        $settings = app(Settings::class);
        $this->form->fill($settings->toArray());
    }

    public function update(): void
    {
        $settings = new Settings();
        foreach ($this->form->getState() as $key => $value){
            $settings->$key = $value;
        }
        $settings->save();
        Notification::make()
            ->title('设置完成')
            ->success()
            ->send();
    }
}

红色代码为出错位置，产生错误的原因是我通过statePath('data')将表单数据保存到$data属性中，但是我的类中却没定义$data属性，在类开始部分添加下面代码即可：

public $data = [];
