Remote script not executed when launch by GUI but works from poller

Hello,

I have a strange behavior, I have a script that was working well since months on my clients, now I simply add an echo in a file within the script to confirm and realize that script is not launched at all.
When i take the command executed (the one displayed in console) and launch it as user centreon-engine directly in poller’s terminal, script is launched and the echo works…

I’m currently wondering what I miss.

Thx for your help.
