Event trigered. Action not executed. Log tell it's OK

[chrisaga]

Steps to reproduce

1. Create a simple workflow (e.g. echo toto>/tmp/1.log) trigered by file creation and/or write an/or rename
2. Create a new text file in nextcloud (or modify it, or rename it)
3. Look at the log for messages with "message":"All qualified flow configurations are going to run" and "message":"All qualified flow configurations are going to run". Messages are there, yeah !
4. See that file /tmp/1.log has not been written :-(
5. Try to write in other directories, try to use a shell script (and trap possible TERM signal), ... same result

Expected behaviour

Action would be executed If not, log shouldn't tell it is but should give a clue about what's wrong

Actual behaviour

Event is triggered (traced in the log), but action is not executed

systemd may jail you into a different subdirectory within /tmp, like /tmp/systemd-private-123456789abcdef0123456789abcde-php-fpm.service-AB0cdE/

I have the same issue with Nextcloud 31. The workflow is being shown as being executed in the log, but no file is being written out into the filesystem.

Thank you. But no, that wasn't it in my case. The issue was that my job execution engine was set by default to Ajax and not chron. After switching over the script executed correctly.

@romangg glad you found the culprit :)
