File access trigger not working

[msi-tl]

Steps to reproduce

1. Create a workflow with trigger "file access"
2. Filter: "filename like /.*/"
3. Script: "echo '%e %i %a' >> /path/to/a/file"
4. Open a file in web or webdav or sync with desktop client
5. Run 'sudo -u www-data php -f /var/www/nextcloud/cron.php' on cli

Expected behaviour

The file should contain a line with the file operation file id and the user name.

Actual behaviour

There are nothing happened.
No log entries. Appears on NC 20 and NC 21
Trigger with file create, change, delete and rename are working fine.

did you check the flow.log in data dir?

[msi-tl]

It seems that flow.log is not be filled by workflow_script. There is not one entry by this app.
Watching with tail -f flow.log and doing the described steps not showing anything including the actions that are working properly (create, change etc.)
The app files_accesscontrol is writing to this log if an access is prevented.

ah, i think the loglevel should be set to 1 for this.

[msi-tl]

Ok, now flow.log is receiving information about the workflow stuff.
But with loglevel 1 there are again no information about the action "access file".
I tried with loglevel 0 and I got the following output from opening a text file in web ui.
Again, there are no information from workflow_script ... :-(
