Snappymail uses '/apps/' instead of '/custom_apps/' path - why?

The Basics

  • Nextcloud Server version (e.g., 29.x.x):
    • 30.0.4.1
  • Operating system and version (e.g., Ubuntu 24.04):
    • Ubuntu 22.04
  • Web server and version (e.g, Apache 2.4.25):
    • Apache (docker)
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • Caddy
  • PHP version (e.g, 8.3):
    • ``
  • Is this the first time you’ve seen this error? (Yes / No):
    • Yes
  • When did this problem seem to first start?
    • After moving from native installation to docker
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
    • docker compose
  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • No

Summary of the issue you are facing:

I recently moved my Nextcloud instance from a native installation on Ubuntu into a docker-compose setup. Now, Nextcloud tries to find the files of the app snappymail in the wrong location:
/apps/snappymail/app/snappymail/v/2.38.2/static/js/min/libs.min.js
while it should be looking in
/custom_apps/snappymail/app/snappymail/v/2.38.2/static/js/min/libs.min.js.
I therefore get an error 404 when trying to access the snappymail app. Removing and reinstalling the app doesn’t help. Where are these paths saved? Is there a cache I can clear, maybe in the database?

I just looked at other apps from the custom_apps folder. They are all opened on paths starting with /apps/ instead of /custom_apps/. But they work well, including memories, deck, etc. I do have an access problem when it comes to onlyoffice, however. Maybe that’s related.

I would highly appreciate any help :slight_smile:

Tips for increasing the likelihood of a response

  • Use the preformatted text formatting option in the editor for all log entries and configuration output.
  • If screenshots are useful, feel free to include them.
    • If possible, also include key error output in text form so it can be searched for.
  • Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.

From a quick look at the code, it looks like snappymail internally saves this in a setting called app_path which looks like it should be available in the snappymail internal admin screen:

Thanks a lot. How the hell did I miss that? I looked at the settings but must have missed it. I changed it to /custom_apps/snappymail/app/ and now everything works well.

I’m still confused why this is necessary at all and why only snappymail is served on /custom_apps/ when all other custom apps located in the same directory are served in /apps/. This doesn’t really make sense to me. Especially because I explicitly set the url parameter in the nextcloud config for the custom_apps to custom_apps. Hence, I would expect that all custom apps are also served there.

Does anyone have an intuition as to why this is? As I said in the main question, I have the feeling that this could be the reason why I have issues with onlyoffice.

Some of the settings I set in the config.php file don’t seem to have an effect. Could it be that there is some kind of cache e.g. in the database from my original installation that I would have to clear?

Thanks in advance again!
