imagemagick convert script doesn't work

Steps to reproduce

1. Install external scripts
2. Add automated tagging to uploaded files
3. Run the command 'convert %x -interlace plane -strip -quality 80 -resize 1000x1000> $(basename %x)_1.jpg' on files that are tagged accordingly to step 2.

Expected behaviour

Image files should be converted according to command settings and have it's original name with the suffix '_1'. This works properly when the command is run directly at the server.

Actual behaviour

Nothing happens at all - flow log is empty. The automated tagging applies, but not the external script.

Are you using external storage, if yes which one: Testing on Local but the plan is to have this applied on files in external storage (SMB)

Are you using encryption: no

Le payload nomme l’application workflow_script et la commande ImageMagick, mais n’indique aucun fichier source ni aucun test. Commencez par reproduire la commande via le tagging automatisé et examinez le flux ainsi que les journaux du serveur ; c’est terminé lorsque le script externe s’exécute et crée le fichier converti avec le nom d’origine suivi du suffixe _1.
