|---|---|---|---|---|---|
region AWS region (overrides the connection). | string | No | — | — | — |
load_balancer_arn Filter by load balancer ARN. | string | No | — | — | — |

In a technical demo we add the Elastic Load Balancing connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
