Description

I am getting an exception when trying to parse PDF

Exception

Missing catalog.

 return $pages;
} elseif (isset($this->dictionary['Page'])) {
// Search for 'page' (unordered pages).
$pages = $this->getObjectsByType('Page');
return array_values($pages);
} else {
throw new \Exception('Missing catalog.');
}
}

Research direction

Start by tracing the PDF parsing path around the shown getObjectsByType('Page') call and the Missing catalog exception. Reproduce the failure with the affected PDF, which is not included here, and determine what input causes the catalog lookup to fail; done means the reported PDF parses without this exception.
