According to nextcloud.log the file files_pdfviewer-public.js is missing:

{
    "reqId": "hisLNxFNFjl13wRNglUg",
    "level": 3,
    "time": "2024-11-07T13:59:13+00:00",
    "remoteAddr": "**",
    "user": "--",
    "app": "jsresourceloader",
    "method": "GET",
    "url": "/index.php/s/**",
    "message": "Could not find resource files_pdfviewer/js/files_pdfviewer-public.js to load",
    "userAgent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:132.0) Gecko/20100101 Firefox/132.0",
    "version": "29.0.9.2",
    "data": {
        "app": "jsresourceloader"
    }
}

And indeed, the file is missing in Nextcloud 29.0.9.

Nextcloud 29.0.8:

$ unzip -l nextcloud-29.0.8.zip | grep files_pdfviewer-public.js

     1683  2024-10-10 11:13   nextcloud/apps/files_pdfviewer/js/files_pdfviewer-public.js.LICENSE.txt

Nextcloud 29.0.9:

$ wget https://download.nextcloud.com/server/releases/nextcloud-29.0.9.zip
$ unzip -l nextcloud-29.0.9.zip | grep files_pdfviewer-public.js

Seems to affect 29.0.9 only.
Both 30.0.2 and 28.0.12 seems OK.

EDIT: Confirmed, #1076 is the cause (files were deleted).

A potential fix is in #1081

Yeah this will fix it. 👍
For those affected, you'll have to wait for v29.0.10.

[szaimen]

Fixed via #1081

Local workaround: I copied the files_pdfview directory from 29.0.8 into 29.0.9.

[Dennis1993]

I copied the files in apps/files_pdfviewer/js too and it works now :)

[Githopp192]

same: nc 29.0.9, PHP 8.3

I copied the files in apps/files_pdfviewer/js too and it works now :)

yes, workaround is working - copied from backup: cp -p ...backup/apps/files_pdfviewer/js/files* ..../apps/files_pdfviewer/js

You need to re-login to make it to work
