ParsingError: Optional Content PDF - with some PDF files uploaded

[MatteoVella]

After uploading some PDF files, during the process of combining two pdfs, the process crashes and returns the following error:

CombinePDF::ParsingError: Optional Content PDF files aren't supported and their pages cannot be safely extracted.

I attach below one of the files that returned the error:
pdf_test.pdf

While other PDF files like the following completed the process without any errors:
pdf_test_2.pdf

What could the error be related to?

Hi @boazsegev, can you help me, please?

Hi @boazsegev, any news from this issue?

Let me know, thanks

Hi @MatteoVella

Did you try allowing optional content (see Known Limitations)?

filename = 'pdf_test.pdf'
CombinePDF.load(filename, allow_optional_content: true).

For me it works fine once that option is enabled.

thank you @boazsegev
we're using both methods

CombinePDF.load

to load file from a local path
and

CombinePDF.parse

to load a file via http
can we use allow_optional_content: true with both methods?

[boazsegev]

Yes, the extra options are passed through to the parse method.

Essentially load is just parse with an IO.binread.
