"Error: invalid page number: 2"

[Jap2-0]

I was trying to open one of my go-to pdfs for stress testing, but this seems to occur when trying to open any pdf in Firefox (nightly).

Stack trace:

Nevermind, I also see this in Edge at https://mupdf.com/wasm/demo/index.html.

Actually, this is dependent on the pdf I'm testing with. (Examples coming shortly.)

I'm getting an error trying to download your PDF, can you attach the files another way?

This should now be resolved for you - please recheck, we just had to align that live demo page with what we have on the repo in examples/simple-viewer.

Please confirm it works and we can close this issue - thanks!

Yep, that fixes it.

(Just as a side note—feel free to ignore this—if you want an absolute torture test for PDF readers to play around with, check out https://drive.google.com/file/d/1GQTR_epMR0rdkkDiW-C_3HlAgao7sgb1/view. I won't blame you for not looking at it, both Acrobat and Firefox have difficulty rendering it.)
