ECLI communicates to Autosys using the Command Sponsor binaries. Command from WCC is being passed thru iGateway to the Command Sponsor binaries who builds environment to execute the autosys command. It will check the file 'instance2script.map' to see if instance and it's script path is defined.
Also it requires an entry that will execute the autosys command also called AutosysCommandWrapper. This line was missing in instance2script.map file.
