The output (i.e. module: ec2_snapshot) of a registered variable (i.e. ec2_snap) returns multiple members.
Playbook is:

Error making code:

ec2_snap registered variable is having details of each of two snapshots in a relevant array element. How to create loop on them?
Short Output is as follow:
{
“changed”:false,
“ec2_snap”:{
“changed”:true,
“msg”:“All items completed”,
“results”:[
{ },
{ }
]
}
}
The extended output is as follow:
