ssm doesn't handle longer instance ID's

[jerm]

$ aws ssm send-command --instance-ids i-065d9ed12b63cd03d --document AWS-UpdateSSMAgent

Parameter validation failed:
Invalid length for parameter InstanceIds[0], value: 19, valid range: 10-10

Thanks for reporting! Cross-service dependencies like this can be problematic

Yeah, this is causing issues for us since aws is transitioning to a longer ID format.

The SSM model has been fixed as of 1.10.1

I'm experiencing a similar error. My instance id is the new longer version, i.e. i-00f91d30c45259a35. Specifically, the error is: "Invalid length for parameter InstanceIds[0], value: 19, valid range: 1-16". The awscli command is: "aws autoscaling detach-instances". It doesn't like my long instance id.

@tlhumphrey2 I was having a similar error with this command:

aws autoscaling terminate-instance-in-auto-scaling-group ...

After reading #1954 I upgraded my awscli to the latest version and the problem is resolved.
