aws-ha-update gets wrong instance-id

[mtb-xt]

Hello.

For some reason the script adds an extra " sign and next commands are failing because of that:

[user@shinkiro aws-ha-release]$ ./aws-ha-release.sh -a prod_media_asg -r ap-southeast-2 -t 10 -i 400 
The list of Instances in Auto Scaling Group prod_media_asg that will be terminated is below:
i-670d77b9"
i-2fa11df0"
i-1da11dc2"
i-2e0278f0"

prod_media_asg has reached a desired-capacity of 5. aws-ha-release.sh can now remove an Instance from service.
Instance i-670d77b9" will now be deregistered from ELBs "prod-media-elb."

A client error (InvalidInstance) occurred when calling the DeregisterInstancesFromLoadBalancer operation: InvalidInstance found in [i-670d77b9"]. Invalid id: "i-670d77b9"" (Service: AmazonEC2; Status Code: 400; Error Code: InvalidInstanceID.Malformed; Request ID: 367c7041-5d0f-4c79-90bf-7a00f48761f0)

Can you show the output of the following command:

aws autoscaling describe-auto-scaling-groups --auto-scaling-group-name "prod_media_asg" --region ap-southeast-2

Also have you given the Ruby version a shot? It uses the aws sdk gem which is a bit more reliable than their CLI.

Yes, the Ruby version works fine, I use that at the moment.

The output of the command:

[user@shinkiro ansible]$ aws autoscaling describe-auto-scaling-groups --auto-scaling-group-name "prod_media_asg" --region ap-southeast-2
