Enum inside blade wich called by job

in my controller i call a job:

SendOfferEmail::dispatch($offer, $request->all());

then my job calls a load pdf by Dompdf:

$pdf= PDF::loadView('pages.offers.pdf', [
				 'offer' => $this->offer, 
				 'rows'  => $rows
]);

in my blade i call the enum:

@if ($row->type == \App\Enums\RowType::X->value)
							x
@endif

Then the job failed with message:

ParseError: syntax error, unexpected identifier "RowType" in /var/www/vhosts/****/app/Enums/RowType.php:5

my enum php file:

<?php 

namespace App\Enums;

enum RowType: string
{
    case X      = 'x';
    case Stuks  = 'stuks';
    case Post   = 'post';
}
