Hey thanks for pointing that one out ! i did used the wrong steam ID , thanks !
After i changed it i noticed i still got the error ,
after reading and reading and reading some more i found out in a post
that essentialmode5 is blocking this command ,
see post : FXServer is blocking a command?
VespuraRegular tells them :
Alright I think I know what the issue is. Because it’s being executed by a resource - it’s also executed by the system.console group but FIRST it’s executed as your resource - you need to make sure that you allow that resource to execute that command.
So in your permissions section in your server.cfg file make sure to put something like this:
add_ace resource. command.add_principal allow
Edit: I’m not 100% sure if this will work, so correct me if I’m wrong
So i added to server.cfg :
nested configs!
#exec server_internal.cfg
add_ace resource.essentialmode command.add_principal allow <—
Now the error is gone ! 
Thanks for the help !
