Description

Hello,

I would like to run a command using NCF method command execution which has 2 arguments like so:

/usr/local/sbin/command.name.sh ${node.properties[SERVER][0]} ${node.properties[SERVER][1]}

node property SERVER is a json

["server0", "server1"]

the command executes successfully, although i get some error messages on the agent:

error: Broken variable expression, index brackets do not balance, in 'node#properties[SERVER][0_'
error: Broken variable expression, index brackets do not balance, in 'node#properties[SERVER][1_'

Please fix this bug in NCF.
Thanks,
Ferenc

Hello Ferenc!

Is it possible to send us the technique file generated ? or at least the extract of the command_execution method call in the technique file ?

The file is located in /var/rudder/configuration-repository/ncf/50_techniques/<bundle_name>/<bundle_name>.cf

I'm rejecting this one, we changed both agent and implementation on ncf, so i'm pretty confident it either succeed, or fail in a totally different way
