My project was written with Livewire

For Google Recaptcha, I use https://github.com/biscolab/laravel-recaptcha

This is the code of the controller:

class ContactForm extends Component
{
    public $name;
    public $email;
    public $phone;
    public $message;
    
    protected $rules = [
        'name' => 'required',
        'email' => 'required|email',
        'phone' => 'required',
        'message' => 'required',
        'g-recaptcha-response' => 'recaptcha',
    ];


    public function render()
    {
        return view('livewire.contact-form');
    }

    public function save(){
        $this->validate();
        Contact::create([
            'name' => $this->name,
            'email' => $this->email,
            'phone' => $this->phone,
            'message' => $this->message,
        ]);
        session()->flash('status', 'Thanks!');
    }
}

This HTML form code:

<form id="contact_form" wire:submit="save" method="post" id="dreamit-form" class="@if ( Config::get('app.locale') == 'fa') text-right @endif">
                            @csrf

                            <div class="row">
                                <div class="col-lg-6">
                                    <div class="form_box mb-30">
                                        <input type="text" wire:model="name"  placeholder="{{ __('messages.contactPage_form_input_fullname') }}" >
                                        @error('name') <span class="text-danger">{{ $message }}</span> @enderror
                                    </div>
                                </div>
                                <div class="col-lg-6">
                                    <div class="form_box mb-30">
                                        <input type="email" wire:model="email" placeholder="{{ __('messages.contactPage_form_input_email') }}" >
                                        @error('email') <span class="text-danger">{{ $message }}</span> @enderror
                                    </div>
                                </div>
                                <div class="col-lg-6">
                                    <div class="form_box mb-30">
                                        <input type="text" wire:model="phone" placeholder="{{ __('messages.contactPage_form_input_phone') }}" >
                                        @error('phone') <span class="text-danger">{{ $message }}</span> @enderror
                                    </div>
                                </div>

                                <div class="col-lg-12">
                                    <div class="form_box mb-30">
                                        <textarea wire:model="message" id="message" cols="30" rows="10" placeholder="{{ __('messages.contactPage_form_input_message') }}" ></textarea>
                                        @error('message') <span class="text-danger">{{ $message }}</span> @enderror
                                    </div>
                                    {!! htmlFormSnippet() !!}
                                    <div class="quote_btn">
                                        <button class="btn" type="submit">{{ __('messages.contactPage_form_btn_submit') }}</button>
                                    </div>
                                </div>

                            </div>
                        </form>

And this error that I receive after registering the form:

No property found for validation: [g-recaptcha-response]
