Is there anything available to display error code in luman laravel while file uploading to validated the file size and file type?

Am new for luman laravel framework and i worked with file uploading concept with file type and file size validation.

$this->validate($request, [
            'profile_picture' => 'required|mimes:jpeg,png,jpg,gif,svg|max:100',
            'pancard_image' => 'required|mimes:pdf,jpeg,png,jpg|max:100',
            'national_id_image' => 'required|mimes:pdf,jpeg,png,jpg|max:100',
            'income_proof_image' => 'required|mimes:pdf,jpeg,png,jpg,doc,docs,xlsx|max:100',
            'address_proof_image' => 'required|mimes:pdf,jpeg,png,jpg|max:100'
        ]);

Am using the validation with above code and my question is how can i display error message with error code like core php file uploading concept.suggestions welcome.
