I'm facing the same issue.. I'm using Ubuntu 18.10

[cndouglas]

Please update to the latest release version (0.56.12). The problem (#1287) has been fixed.

[michelecafagna26]

Great! it works fine

This issue is still present in Version 0.61.51 Chromium: 73.0.3683.75 on macos. Let me know if you need further information.

The cookies seems to not be included on the request made for the pdf file, which ends up resulting in a redirect to a login page.

I also see this issue with Version 0.65.120 Chromium: 75.0.3770.90 (Official Build) unknown (64-bit) even with all shields down.

@LefterisJP do you have more information? (not sure if the site you are using requires a login). Would be great if we had some way to reproduce on our side

[LefterisJP]

Yep. So the site is actually mine. It does require a login and it's a django website (not live yet) so the test code is all local.

The url requires login access so cookies are involved.

The response is a pdf. In python code it's the following:

...
...
...
    with fs.open(internal_filename) as pdf:
        response = HttpResponse(pdf, content_type='application/pdf')
        response['Content-Disposition'] = f'attachment; filename="{external_filename}"'

    return response

Anything else I can do to help?

@LefterisJP nice! ok so the only thing I would ask would be: can you try Nightly? We removed PDF.js in favor of PDFium. If it works in Chrome/Chromium, it should now work for you 😄

This code will eventually make it's way into the release channel (currently, we're on 0.65.x and the fix was in 0.68.x) - estimated ship date August 20th

@bsclifton Done. Used latest AUR nightly package in Archlinux so that makes it 0.68.60-1.

There the problem is gone. Clicking on the URL downloads the pdf, just like in Chromium and then you can click on the download to see a preview which renders just fine. 👍

@LefterisJP awesome! thank you so much for confirming 😄 Feel free to stick with Nightly or you can ride it out (and continue to use the more stable Release channel). Thanks again 😎
