app not deploying to client

1 Serverclass.conf in ~splunk/etc/system/local using clientName attribute

placeholder app in ~splunk/etc/deployment-apps/placeholder [global] whitelist.0=* stateOnClient = enabled [serverClass:base-xyz] filterType = whitelist whitelist.0 = xyz-common-apps [serverClass:base-xyz:app:placeholder]

2 deploymentclient.conf on deployment client /etc/system/local

[deployment-client] disabled = 0 clientName = xyz-common-apps [target-broker:deploymentServer] targetUri = x.y.z.d:8089

3 list deploy-clients in DS shows deployment client with right client name connected

But still no app has been deployed to client although app is available

4 restarted both sides

Appreciate inputs

Thanks
