^ my code trying to create the listener

Just a note that

elasticloadbalancingv2

is ALB/NLB, not classic load balancer - I assume that's what you want?

oh

Here's an example of using this:

const listener = new aws.elasticloadbalancingv2.Listener(`${name}metabase`, {
            loadBalancerArn: loadbalancer.arn,
            port: 443,
            protocol: "HTTPS",
            certificateArn: certificate.arn,
            defaultAction: {
                type: "forward",
                targetGroupArn: targetgroup.arn,
            },
            // Require the use of SSL/TLS v1.2 or higher to connect.
            sslPolicy: "ELBSecurityPolicy-TLS-1-2-2017-01",
        }, { parent: this, dependsOn: [certificateValidation] });
        const httpRedirectListener = new aws.elasticloadbalancingv2.Listener(`${name}metabase-redirecthttp`, {
            loadBalancerArn: loadbalancer.arn,
            port: 80,
            protocol: "HTTP",
            defaultAction: {
                type: "redirect",
                redirect: {
                    protocol: "HTTPS",
                    port: "443",
                    statusCode: "HTTP_301",
                },
            },
        }, { parent: this });

I think I need a classic load balancer (just basing off what we already have). Is it the "applicationloadbalancing" module or "elasticloadbalancing" (not v2)?

Yep -

elasticloadbalancing

. Naming here is unfortunate overall, but aligned with what AWS APIs chose to do when ALB/NLB were introduced.
