Hello all,

I am trying to use group vars with dynamic inventory file **ec2.py** and It is not working. Can anyone help me how can I use group vars with dynamic inventory?

i am doing like

- hosts: my\_host:tag\_env\_uat

and in group vars, I defined like group\_vars/tag\_env\_uat/vars.yml

the error is

fatal: [192.168.33.10] =\> {‘msg’: “AnsibleUndefinedVariable: One or more undefined variables: ‘dict object’ has no attribute ‘groups’”, ‘failed’: True}  
fatal: [192.168.33.10] =\> {‘msg’: ‘One or more items failed.’, ‘failed’: True, ‘changed’: False, ‘results’: [{‘msg’: “AnsibleUndefinedVariable: One or more undefined variables: ‘dict object’ has no attribute ‘groups’”, ‘failed’: True}]}
