I’m trying to write a shell script to generate a pdf file using CakePdf. When I run the shell script it runs fine the first time, but on subsequent runs it has an error. After waiting a minute or two, I can run it again without changing any code and it runs once again. But only once, and again I have to wait a minute or two before it will work. Any ideas as to what could be causing this?
Thanks
I’m using Cake 3.3.3.
The function I call in my shell.
public function makePdf()
{
Configure::write('CakePdf', [
'engine' => [
'className' => 'CakePdf.WkHtmlToPdf',
'binary' => '/path/to/wkhtmltox/bin/wkhtmltopdf',
],
'margin' => [
'bottom' => 0,
'left' => 0,
'right' => 0,
'top' => 0
],
'pageSize' => 'A6',
'orientation' => 'landscape'
]);
$CakePdf = new \CakePdf\Pdf\CakePdf();
$CakePdf->template('template_name', 'layout_name');
$output_file_path = ROOT . DS . 'files' . DS . '123.pdf';
$CakePdf->write($output_file_path);
}
The error I see if I try to run the function twice without waiting for a minute or two.
Error: [Cake\Core\Exception\Exception] System error <pre>Exit with code 1 due to network error: ContentNotFoundError
