…redentials The EC2 runner client read the AMI id SSM parameter with the shared default SSM client, i.e. the credentials of the runtime role. With scale sets that is the controller task role, whereas only the compute provider role, which the controller assumes to launch instances, is allowed to read an external AMI id parameter. createEc2RunnerClient now accepts an optional SSM client used for that lookup (including the on-demand failover), and the scale-set provider passes the one built with the assumed credentials. The Lambda control plane is unchanged.
