Hi,

For the past few days I am getting the following error when running ansible playbooks using the AWS cloud modules or when directly running the ec2.py file with the --refresh-cache command from my local machine:

ap:~ ap$ /ansible/inventory/ec2.py --refresh-cache  
Traceback (most recent call last):  
File “/ansible/inventory/ec2.py”, line 1510, in   
Ec2Inventory()  
File “/ansible/inventory/ec2.py”, line 186, in **init**  
self.do\_api\_calls\_update\_cache()  
File “/ansible/inventory/ec2.py”, line 492, in do\_api\_calls\_update\_cache  
self.get\_elasticache\_replication\_groups\_by\_region(region)  
File “/ansible/inventory/ec2.py”, line 722, in get\_elasticache\_replication\_groups\_by\_region  
self.add\_elasticache\_replication\_group(replication\_group, region)  
File “/ansible/inventory/ec2.py”, line 1198, in add\_elasticache\_replication\_group  
dest = replication\_group[‘NodeGroups’][0][‘PrimaryEndpoint’][‘Address’]  
TypeError: ‘NoneType’ object has no attribute ‘ **getitem** ’

This issue seems to be go away when running from an Ec2 instance in the AWS account.

I have the latest EC2.py and EC2.ini files, ansible version is 2.2.0.0 and boto3 is installed and I do set the valid AWS credentials before running the playbook,

Any ideas on what’s going on?
