execCommand() is not working in workflow.

Hello Everyone,

execCommand() is not working in a JS activity in a workflow on application server.

There is on-premise instance and build is 9032.

Configuration is serverConfig.xml:

<!-- Command execution

         blacklistFile :  Path to the file containing the commands to blacklist

         user :  Execute commands as a different user -->

    <exec blacklistFile="" user=""/>

JS Code:

logInfo(execCommand("cd",true));

Error:

BAS-010076 Cannot execute command 'cd' (err=2, the system cannot find the file specified.).

I am getting same error for every commands.

Please let me know if you have any question.

Thanks.

Parvesh.
