The Basics

  • Nextcloud Server version (e.g., 29.x.x):
    • 30.0.2
  • Operating system and version (e.g., Ubuntu 24.04):
  • Web server and version (e.g, Apache 2.4.25):
  • Reverse proxy and version _(e.g. nginx 1.27.2)
  • PHP version (e.g, 8.3):
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • The server is hosted by Ocloud. I don’t have this information, or I don’t know where to get it from

Summary of the issue you are facing:

I am trying to set up a Nextcloud Flow to perform an action when specific files are uploaded.
I have configured a test flow with the following settings:
Trigger (When): File created
Condition (and): File MIME type is PDF Documents
Action (Then): Run script

For the “Run script” action, I’ve used the following minimal script to test its functionality:
echo “— FLOW SCRIPT EXECUTED AT $(date) —” >&2 exit 0
This should write a line in the logging.

I can successfully save the flow. But when I want to trigger it by uploading a PDF file, the expected line “— FLOW SCRIPT EXECUTED AT [Date/Time] —” does not appear in the Nextcloud logs under “Administration → Logging”.

I’m not sure if the script doesn’t work or if the expected line may be written to a different location (which I don’t have access to) — or not written at all.

Could someone check if I did a mistake or did I misunderstand how this flow works?

The output of your script isn’t logged by Nextcloud itself based on the code:

If you set loglevel to INFO level (1) you’ll get notification the script ran in the Nextcloud log, but handling the output of your script is up to you. You could, for example, output it to your own log file.
