Unable to use 'repo' directive in kickstart

Issue

• I am trying to use the 'repo' directive in the kickstart config file to install errata at the time of OS installation, keep getting an error message.
• The message I get is "You have specified that the package 'repo --name=sample --baseurl=file:///tmp/repos/sample/' should be installed. This package does not exist. Would you like to continue or abort this installation?"
