Original GitHub issue: https://github.com/modoboa/modoboa/issues/3654

Impacted versions

OS Type: Debian
OS Version: 12.11
Database Type: MySQL (MariaDB)
Database version: 10.11.11
Modoboa: 2.4.9
installer used: No (used installer a few years ago, manually updating since..)
Webserver: Nginx

Steps to reproduce

new frontend -> Identities, try to download any user pdf credential.

Current behavior

trying to download any pdf credential from any existing identities and nothing happens. same with new users created. no errors/messages shown. just seems identities page is refreshing after pressing "Download PDF Credentials"..
pdf files do exist in /srv/modoboa/pdfcredentials (modoboa:modoboa perms)

uwsgi log :
example.net [pid: 3148328|app: 1|req: 11/29] xxx.xxx.xxx.xxx () {58 vars in 1030 bytes} [Sat Aug 2 15:57:55 2025] GET /api/v2/accounts/?page=1&page_size=25 => generated 19829 bytes in 272 msecs (HTTP/2.0 200) 6 headers in 205 bytes (1 switches on core 0)

pdf credentials download was working fine in old frontend.

btw, even when manually downloaded (eg scp/rsync from server), pdf files can't be opened.. (maybe different issue?) eg.

$ file user@example.com.pdf
user@example.com.pdf: data

$ pdfinfo user@example.com.pdf
Syntax Warning: May not be a PDF file (continuing anyway)
Syntax Error (13): Illegal character '{'
Syntax Error: Couldn't find trailer dictionary
Syntax Error: Couldn't find trailer dictionary
Syntax Error: Couldn't read xref table

Expected behavior

download user credentials pdf in browser.
