File created trigger is not fired when the file is created locally on the server

[Arduous]

Hello,

I have a MFP that is configured to scan and push pdf files to a SMB folder within the data files of an user on the Nextcloud server The file permission and ownership (www-data) are taken care of. It seems that the "File created" event is not triggered.

Steps to reproduce

1. Create a flow that performs some action on file named test.txt with the trigger "File created"
2. A test.txt file is created within the web UI or a synchronized folder
3. Force cron execution sudo -u www-data php -f /var/www/nextcloud/cron.php
4. Verify that the flow performs adequately
5. Create a file directly on the server with e.g.: echo "Hello, world!" | sudo -u www-data tee /var/www/nextcloud/data/userxyz/files/scan/test.txt
6. Force cron execution sudo -u www-data php -f /var/www/nextcloud/cron.php

Expected behaviour

The flow is triggered and performs per expectations.

Actual behaviour

The flow is not triggered

I am seeing the same issue. I scan a document as PDF with a HP multifunctional printer and store it in a directory i.e. /var/www/nextcloud/data/user/files/scaninbox shared via samba. I would like to execute a script that OCRs the PDF and adds a text layer so it can be searched via elastic search. Unfortunately the script is never executed although sudo -u www-data php -f /var/www/nextcloud/cron.php is executed.

@mlsxlist Do you use nextcloud for storing the file? Or do you store it using the operating system for that? In latter case, have you tried adding the file to nextcloud afterwards? sudo -u www-data -s /usr/bin/php /var/www/nextcloud/occ scan userxyz/files/scan/test.txt

[benjaminfrombe]

same issue here, running occ files:scan (--all / user / --path) does not trigger the workflow. I would like to achieve exactly the same thing:

my scanner uploads the pdf via ftp, and I would like to run a workflow to OCR the pdf.

it does work when I upload the pdf using the normal UI.

I run "occ scan" as a cron job, but it does no trigger the workflow.

[k1l1]

Do you know if a workflow is triggered if you add the file via the webdav api? eg. try to use something like curl -X PUT "https://mycloud.net/remote.php/webdav/folder/file.txt" –data-binary @"file.txt" -u myusername

[benjaminfrombe]

yes it is, that's currently my workaround

I'm using a samba share as external_storage to access scanned hardcopies (my printer/scanner is only able to use samba as network storage). Would be great if files:scan would emit a postCreate to get flows triggered for external storages.

Unfortunately I cannot use webdav with my printer/scanner. Is there any other workaround?
