Unable to start nodemanager on 12.2.1.3 Basic domain due to missing DemoIdenity.jks file under domai

I created a weblogic domain using both Weblogic Server installer and FMW_WLS_infrsstructure installer but neither of them created the Demoidentity.jks file under the domain_home/security.

I am using the basic wlst script to create the domain , please advise if we need to add or make any changes to the domain script.

selectTemplate("Basic WebLogic Server Domain")

loadTemplates()

set('Name', 'test')

cd('Security/test/User/weblogic')

set('Password', 'weblogic1')

cd('/Servers/AdminServer')

set('ListenAddress', '')

set('ListenPort', 7001)

setOption('OverwriteDomain', 'true')

writeDomain('/u01/domains/test')

when i try to start the nodemanager I am getting below exception:
