Ansible not recognizing hosts for aws ec2 hosts

[Huda]

Hello,

Could someone please help with the following issue:

when I run any of the ansible list hosts commands, it doesn't show the host that's listed in the file. What am I doing wrong? I'm able to ssh passwordless to this host.

I've the inventory.txt file:

This is the snippet of /etc/ansible/ansible.cfg 

[defaults]

# some basic default values...

inventory      = /home/ec2-user/ansible_work/inventory.txt

[inventory]

enable_plugins = aws_ec2

=============================

this is inventory file: /home/ec2-user/ansible_work/inventory.txt

[servers]

devtest ansible_host=99.9.99.99   ansible_user=ec2-user

==========================

and i got this error:

$ ansible all --list-hosts
