ValueError when running PdfReader.outline

[CactusJackFX]

When I go to get the Bookmarks from this PDF I get the following error message:
ValueError: not enough values to unpack (expected 3, got 1)

I have attached a copy of the code on how I opened up the file along with the error and where numbers on where the errors where it's happening. I can't attach a copy of the PDF yet, but I will work on it.

@CactusJackFX
Can you please precise the version you are using
also if you prefer you can send the document privately to @MartinThoma info@martin-thoma.de

I'm currently using version 3.8.1. I just upgraded to that one from version 3.4.0, and I'm still getting the same error. I will work on getting approval to send you one of the two documents that I have that are currently getting that error message.

I'm not able to provide a copy of the PDF due to PII, but I did find this when reviewing the document deeper.

So it might be the security is causing the issue in not reading the bookmarks.

I cannot come to any conclusion without the pdf
Subsequently I will close this issue

I run into this same problem. check this pdf please: https://github.com/xrkk/tmpppppp/tree/main

PyPDF2 version：3.0.1

[pubpub-zz]

please upgrade to pypdf and to latest update. PyPDF2 is depreciated.

I get the same error message on pypdf version 3.8.1 using the sample PDF that xrkk provided.

PDF Splitter Version: 1.2.3 last changed on: 05/15/2023 using PyPDF version 3.8.1.

not enough values to unpack (expected 3, got 2)
File: C:\Input\2021 ---- book - Security of biquitous Computing Systems.pdf can't read bookmarks from source pdf file.

With that sample file, this issue should be re-opened.

I've found the issue : the last parameter (zoom) in XYZ destination is optional. The code forgot that. a PR has been produced

[MartinThoma]

Thank you @pubpub-zz for taking care of this issue <3

[MartinThoma]

The PR was just merged and will be part of pypdf > 3.8.1. I will make the release on Sunday.
