I’m a greenhorn…I have this problem where I want the user to input either dev or prod in an env prompt then I take that and access a dictionary to get its custom properties. it works fine if I hardcode {{ dev.ip }} but if I do a lookup it says variable dev.ip not found.  
Also, let me know if there is a better way. Only gotcha is this if for networking so the target is always localhost and then it does api calls.

- hosts: localhost  
gather\_facts: no  
vars\_prompt:
- name: username  
prompt: “Username”
- name: password  
prompt: “Password”
- name: env  
prompt: “Environment”  
vars:  
prod:  
ip: ‘1.1.1.1’  
dev:  
ip: ‘10.130.155.53’
- name: Query tenant customer-xyz  
aci\_tenant:  
host: “{{ lookup(‘vars’, env + ‘.ip’) }}”  
#host: “{{ dev.ip }}”  
username: “{{ username }}”  
password: “{{password}}”  
state: present  
validate\_certs: false  
register: my\_tenant

fatal: [localhost]: FAILED! =\> {“msg”: “The task includes an option with an undefined variable.  
The error was: No variable found with this name: dev.ip\n\nThe error appears to be in ‘/var/lib/awx/projects/aci-dev/querytenant.yml’:  
line 19, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n  
var: host\n - name: Query tenant customer-xyz\n ^ here\n”}
