调用未定义的方法Dompdf\\FrameDecorator\\Page::add_line()

我试图发送一封包含2个pdf附件的电子邮件,但在控制器中调用getRejectedReport方法时,它返回了错误信息,即调用未定义的方法Dompdf\FrameDecorator\Page::add_line(),而另一个方法getReport成功运行并生成作为附件放入电子邮件的pdf。

得到这个 Call to undefined method Dompdf\\FrameDecorator\\Page::add_line()

我对这两个pdf刀片文件有几乎相同的代码和相同的逻辑。这是我的示例代码。。。。

class ChecklistController extends AppBaseController
{
    protected $pdf;

    public function __construct(
        ComplaintRepository $compRepository,
        PDf $pdf,
    ) {
        $this->compRepository = $compRepository;
        $this->pdf = $pdf;
    }

    public function getReport($id, $type = 'stream')
    {
        $view = 'pdf.report';
        $filePath =  app()->basePath() . '/public/uploads/pdf';

        $pdf = $this->pdf->loadView($view, [
            'content' => $data, 
        ])->setPaper('a4');

        $pdf->setWarnings(false)->save($filePath);
    }

    public function getRejectedReport($id, $type = 'stream')
    {
        $view = 'pdf.rejected-report';
        $filePath =  app()->basePath() . '/public/uploads/pdf';

        $pdf = $this->pdf->loadView($view, [
            'content' => $data, 
        ])->setPaper('a4');

        $pdf->setWarnings(false)->save($filePath);
    }

}
