Hello @oggo Null is possible when IGNITE_HOME variable is not configured. Visor CMD use that variable as a root folder to find configuration files and show they in open command.
Please set IGNITE_HOME variable equal to your application home. Ignite automatically detect the home folder when it contain "bin" and "config" folder. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
