我正在使用Laravel 8和API的工作。我已经创建了表单验证的请求类，但当移动的开发人员点击API验证消息不显示所需的。这是我的控制器方法

public function store(InvoiceStoreRequest $request)
{
    try {
        return $this->responseWithSuccess(true,'Invoice Data',
               $this->invoiceInterface->store($request), Response::HTTP_OK);
    }catch (\Exception $exception){
        return $this->responseWithError($exception->getMessage(),Response::HTTP_OK);
    }
}

这里我使用InvoiceStoreRequest类来验证表单。InvoiceStoreRequest的代码如下

public function rules()
{
    return [
        'id' => ['required', 'string'],
        'invoice_date' => ['required', 'date'],
        'reference_number' => ['required'],
        'vendor_id' => ['required'],
        'invoice_net_total' => ['required','regex:/^\d*(\.\d{1,2})?$/'],
        'invoice_tax_total' => ['required', 'regex:/^\d*(\.\d{1,2})?$/'],
        'invoice_gross_total' => ['required', 'regex:/^\d*(\.\d{1,2})?$/'],
        'item_count' => ['required', 'numeric'],
        'invoice_type' => ['required','regex:(order|refund)'],
        'provider' => ['required'],
        'detail_url' => ['required'],
        'invoice_photo_url' => ['required'],
    ];
}

并且用于显示定制消息，

public function messages()
{
    return [
        'invoice_type.regex' => 'The invoice type format is invalid. Invoice Type should be [order,refund]',
        'invoice_net_total.regex' => 'Invoice Net must be Decimal or Numeric value.',
        'invoice_tax_total.regex' => 'Invoice Tex must be Decimal or Numeric value.',
        'invoice_gross_total.regex' => 'Invoice Gross must be Decimal or Numeric value.',
    ];
}

它在 Postman 上工作正常。但是当移动的开发人员点击API时，他得到了422不可处理实体的错误，但没有显示错误消息。我想显示错误消息。
我该怎么解决这个问题。谢谢
