Laravel：尝试访问 null 类型值的数组偏移量

如何解决Laravel：尝试访问 null 类型值的数组偏移量

我的 livewire 文件中有以下内容用于创建联系人并为他创建新企业。

    public $contact;
    public $entreprise;

 public function saveContact()
{
    $this->validate();

    $newentreprise = Entreprise::create([            
        'nom' => $this->entreprise['nom'],'adresse' => '1','cle' => Str::random(32),'code_postal' => '95959','ville' => 'meknes',]);

    Contact::create([
        'nom' => $this->contact['nom'],'prenom' => $this->contact['prenom'],'e_mail' => $this->contact['e_mail'],'telephone_mobile' => '','telephone_fixe' => '','entreprise_id' => $newentreprise->id,]);

    $this->confirmingContactAdd = false ;

}

联系人创建完美，但我在创建企业时遇到了问题。似乎未正确请求 'nom' 中 $newentreprise 的输入。我哪里有问题？

contact.blade.PHP 显示输入（正确请求接触的 3 个输入）：

    <div class="flex mt-6">
