Automated PDF Conversion in NextCloud 18.0.0 does not work

Nextcloud version (eg, 12.0.2): 18.0.0
Operating system and version (eg, Ubuntu 17.04): CentOS 7.6
Apache or nginx version (eg, Apache 2.4.25): nginx/1.16.1
PHP version (eg, 7.1): PHP 7.3.13

The issue you are facing: Converting an .odt document to PDF with the Automated PDF Conversion app using the Flows feature does not work.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Install the Automated PDF Conversion app.
  2. Tag a document with “pdf”, such as the sample .odt file included with each NextCloud install.
  3. Create a Flow to automatically convert documents that have a tag added. Filter for the tag “pdf”.
  4. The document is not converted, and the error below appears in theNextCloud log.

https://github.com/nextcloud/documentserver_community/issues/10 should be fixed with a newer release. There are also some hints how to debug this issue further (for example checking the binary with ldd to see missing system libraries).

Please note the product name is Nextcloud and not NextCloud.

hi, i’m just testing this functionality from my 18.0.3. The pdf isn’t created. in the log i see the action is triggered. But don’t see any error, what could be wrong? I’m using the default OnlyOffice which is installed within the NExtcloud installation.

i have the same event set for triggering a chat post, that one is working.
in the log i see:
