Hello Punit,

that's not an error. "newdynamicgroup" is empty so it doesn't execute the tasks in that play.

But i was adding host in that play:

add\_host:  
hostname: “test1”  
ansible\_host: “10.1.1.3”  
ansible\_ipaddress: “10.1.1.3”  
groups: ‘newdynamicgroup’

This should add host as well to this group isinit or am I doing something wrong here ?

That doesn't matter as the host list (group newdynamicgroup) is empty when Ansible looks at your play. Which means it  
skips all the tasks.
