- name: Gather EC2 Snapshot Info  
ec2\_snapshot\_info:  
filters:  
“tag:Name”: fortune  
register: snap

- name: AMI registration from EBS Snapshot  
ec2\_ami:  
name: fortune  
state: present  
architecture: x86\_64  
virtualization\_type: hvm  
root\_device\_name: /dev/xvda  
device\_mapping:

- device\_name: /dev/xvda  
volume\_size: 8  
snapshot\_id: “{{ snap.snapshot\_id }}”  
volume\_type: gp2  
delete\_on\_termination: true  
register: ami

I’m receiving this error.

The task includes an option with an undefined variable. The error was: ‘dict object’ has no attribute 'snapshot\_id

I believe is has something to do with my variable. Anyone have an idea?

I’m not familiar with the ec2\_snapshot info module, but the core problem is the registered variable “snap” - which is a dictionary - does not have a key ‘snapshot\_id’.

What I often do in these cases is to add a debug task immediately after the task that registers the variable which simply dumps the value of “snap”. Something like this (not tested):  
`

- name: Debug Snap Task  
debug:  
msg: “ec2\_ami results {{ snap }}”  
`

This should show you whether snapshot\_id exists and how to access it.
