Ansible 2.x - AWS ec2_asg problem -> AttributeError: 'module' object has no attribute 'InvalidInstance'
dav...@pointinside.com
Python 2.7.10
ansible (2.0.0.2)
boto (2.38.0)
botocore (1.3.20)
running the playbook to update an existing autoscaling group, I started getting this error last week:

An exception occurred during task execution. The full traceback is:

AttributeError: 'module' object has no attribute 'InvalidInstance'
fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "invocation": {"module_name": "ec2_asg"}, "parsed": false}
I have tried to change the version of boto and ansible, however the error now persists. I have not been able to identify any root cause or known bug other than the error message. I have tried switching a few options on and off in the playbook such as: wait_for_instances and lc_check.
Thanks!

I can avoid the error if I do not use the option "wait_for_instances" in my Ansible config. So something in this code path is executing the call getting the error. The error itself is a Python/Boto error, as the task really does succeed (although Ansible does not know that).
