Hey @timothyclarke 👋 Thank you for taking the time to raise this! It looks like the underlying type of prod_traffic_route from the AWS Go SDK is type TrafficRoute, which has a field called ListenerArns. This field is where the listener_arns argument name and type comes from, as we try to mirror the underlying SDK/API as much as possible. That said, this seems like something that we should add validation and documentation for, so I'd like to leave this issue open to be addressed.
