Start at plugins/clb_target.go lines 460-483, especially the range loop and the reference to hostId in the DescribeInstancesRequest composite literal. Check the referenced Go range-loop behavior and determine whether the analyzer finding is a bug, mitigated issue, or desirable behavior; done means leaving the corresponding reaction on this issue.
