Built-in CODE Uses Wrong URL for fonts.json #312
Description
Running https://github.com/nextcloud/docker and noticed that the built-in CODE uses https://<Nextcloud Domain>/custom_apps/richdocuments/settings/fonts.json instead of https://<Nextcloud Domain>/apps/richdocuments/settings/fonts.json (as mentioned on https://<Nextcloud Domain>/settings/admin/richdocuments). This causes custom fonts not to be loaded.
richdocuments is indeed installed under /var/www/html/custom_apps so the problem isn't to do with it being under .../apps. I assume Nextcloud now uses ../apps/... for all applications.
I hacked around this with the following addition to my NGINX reverse proxy config. but it's not ideal (a 301 redirect did not work - but that is more of a problem for https://github.com/CollaboraOnline/online):
...
# Hack for redirecting the custom_apps URL for fonts.json to apps to
# fix the built-in CODE server's hard-coded use of the former as
# custom_apps is replaced by apps in the URL for later versions of
# Nextcloud.
location = /custom_apps/richdocuments/settings/fonts.json
{
proxy_pass https://<Nextcloud Domain>/apps/richdocuments/settings/fonts.json;

The line in question where this is set seems to be https://github.com/CollaboraOnline/richdocumentscode/blob/master/proxy.php#L85.

This is also a problem when using nextcloud Snap package together with builtin CODE. In case of Snap packages, bundled Nextcloud read-only apps are served under /apps while other apps are under /ext-apps. Unfortunately CODE deduces richdocuments' fonts.json URL based on richdocumentscode app path, not in the same app path. I worked around hard-coding correct URL in proxy.php, until next update.

I have this same problem with snap nextcloud
There is a bug where snap nextcloud looks for:
/index.php/extra-apps/richdocuments/settings/fonts.json
while it is in:
/index.php/apps/richdocuments/settings/fonts.json
Inspired by https://help.nextcloud.com/t/nextcloud-snap-guide-to-getting-htacces-pretty-urls/213444
I made a workaround by changing
/snap/nextcloud/current/htdocs/.htaccess
by adding at the end of that file the following 3 lines of code:
RewriteEngine on
RewriteCond %{QUERY_STRING} ^$
RewriteRule ^index.php/extra-apps/richdocuments/settings/fonts.json$ /index.php/apps/richdocuments/settings/fonts.json? [L]
after saving one needs to restart the service by:
sudo snap restart nextcloud.apache
Now, the extra fonts that were added in nextcloud administration settings under Office, finally show up in the editor.
I guess after each update this needs to be redone and I guess my workaround has room for improvement?

@etisserant and @JeroenvanderSluijs, if you could give a 👍 on the OP it should hopefully get more visibility.

I was mistaken. The rewrite rule in .htaccess does not do the job. The hard-coding of the URL in proxy.php which I tried first seems to do the job, but it requires a restart of the snap nextcloud (which I did to let the .htaccess change take effect, but in fact the hard-coding in proxy.php did the job).
I added the following lines to /var/snap/nextcloud/current/nextcloud/extra-apps/richdocumentscode/proxy.php after line 87
$remoteFontConfigUrl = escapeshellarg("https://YOUR.DOMAIN.HERE/index.php/apps/richdocuments/settings/fonts.json");
$remoteFontConfig = "--o:remote_font_config.url=" . $remoteFontConfigUrl;
after saving (and given that the command coolconfig update-system-template does not work in snap) it needs
snap restart nextcloud
However, modifying proxy.php seems to result in an error message in the integrity check (INVALID_HASH for proxy.php) in index.php/settings/admin/overview
Also, after adding new fonts in index.php/settings/admin/richdocuments the system needs a snap restart nextcloud
@lzlrd how can your solution be implemented in apache? (What file has apache's reverse proxy config and what code should I put there? )

After the latest snap nextcloud update (nextcloud 31.0.5snap1 rev.48223) the workaround in proxy.php needs to be changed to local host to avoid a 304 error when "COOLWSD HTTP Agent 24.04.13.3" tries to GET the json.fonts file:
$remoteFontConfigUrl = escapeshellarg("https://127.0.0.1/index.php/apps/richdocuments/settings/fonts.json");
Ignore the security warning in /index.php/settings/admin/overview (INVALID_HASH proxy.php)
UPDATE 10 Oct 2025:
Edit this file:
/var/snap/nextcloud/current/nextcloud/extra-apps/richdocumentscode/proxy.php
REPLACE_THESE_LINES
{$_SERVER['HTTP_HOST'] . preg_replace("/richdocumentscode.*$ /", "richdocuments/settings/fonts.json", $_SERVER['REQUEST_URI']));
$remoteFontConfigUrl = escapeshellarg("https://" .
$remoteFontConfig = "--o:remote_font_config.url=" . $remoteFontConfigUrl;
}
BY_THESE_LINES
$remoteFontConfigUrl = escapeshellarg("https://127.0.0.1/index.php/apps/richdocuments/settings/fonts.json");
$remoteFontConfig = "--o:remote_font_config.url=" . $remoteFontConfigUrl;
ENDREPLACEINSTRCUTION
This does the trick for my Snap Nextcloud Hub 10 (31.0.9) install on an almalinux box.

Of course nobody cares, and of course nextcloud-snap did update CODE without asking breaking it further. Tests are overrated.
Here is how I ended this nightmare, in the particular case of nextcloud-snap package:
wget https://github.com/CollaboraOnline/richdocumentscode/releases/download/24.4.902/richdocumentscode.tar.gz, unpack it in/var/snap/nextcloud/current/nextcloud/extra-apps, enable it in NextCloud admin./var/snap/nextcloud/current/nextcloud/extra-apps/richdocumentscode/proxy.php, change$remoteFontConfigUrl = escapeshellarg("https://" . $_SERVER['HTTP_HOST'] . preg_replace("/richdocumentscode.*$/", "richdocuments/settings/fonts.json", $_SERVER['REQUEST_URI']));into$remoteFontConfigUrl = escapeshellarg("https://" . $_SERVER['HTTP_HOST'] . preg_replace("/extra-apps\/richdocumentscode.*$/", "apps/richdocuments/settings/fonts.json", $_SERVER['REQUEST_URI']));snap refresh --hold=forever nextcloud/var/snap/nextcloud/current/nextcloud/config/config.php, and change'writable' => true,into'writable' => false,. Then update the nextcloud snap package, then revert this config.php change otherwise CODE won't start.Hope it helps.
