We are experiencing this problem also. It appears to be the same as #392, #373, #356, and #330. #330 was reported on August 30 of last year.

@k00ni, Is there anything we can do to help get this resolved?

Unfortunately I don't have the time to dive into that, but I will assist any pull request which aims to solve this issue. For what I saw until now, I assume that this library is not be able to parse this kind of files (yet). This functionality must be written first.

pdfparser/src/Smalot/PdfParser/Parser.php

Lines 106 to 117 in 73204b4

	public function parseContent($content)
	{
	// Create structure from raw data.
	list($xref, $data) = $this->rawDataParser->parseData($content);
	if (isset($xref['trailer']['encrypt'])) {
	throw new \Exception('Secured pdf file are currently not supported.');
	}
	if (empty($data)) {
	throw new \Exception('Object list not found. Possible secured file.');
	}

I see now that this issue was first reported in 2014, in the earliest issue that is still open: #30 Also, #209, #192, #185 . It's been reported about 9 times over the course of 7 years. It appears to be a problem with the library not handling PDFs that are have a version > 1.4.

Could you please give us feedback if #400 solves this problem?

[ppritcha]

That solves the problem for us.
