PDFs streaming PDF binary pages instead of images

[DaveAlton]

Steps to reproduce

It looks like the server is not behaving like expected.

This is an example of a streaming URL
https://[server_domain]/opds/v1.2/books/0BSERXJ3JF6AW/pages/0?zero_based=true

M Komga server is returning

{
  "timestamp": "2023-10-20T17:37:04.182+00:00",
  "status": 400,
  "error": "Bad Request",
  "message": "Page number does not exist",
  "path": "/opds/v1.2/books/0BSERXJ3JF6AW/pages/0"
}

When it's a PDF. I tried tweaking the URL to https://[server_domain]/opds/v1.2/books/0BSERXJ3JF6AW/pages/1?zero_based=true
and it responds, but the response is not an image. It returns binary data that seems to be a PDF binary becuase the data starts with

%PDF-1.4
%öäüß
1 0 obj
<<
/Type /Catalog
/Version /1.4
/Pages 2 0 R
>>
...

OPDS PSE only accepts jpeg, png and gif as a response. So even if the page index issue is solved, the returning data is still wrong.

Expected behavior

PDF page streaming should return jpeg, png or gif

Actual behavior

Seems to be streaming a PDF binary

Which client are you using, and what request headers is it sending?

[DaveAlton]

I’m using Panels. I’m unsure what the headers are. I initially filed a ticket with them and they were actually the ones that did this troubleshooting. They then referred me to file a ticket with you.

Thanks for the details, I'll look into it.
