Error when applying Terraform configuration for ALB: ListenerNotFound

Terraform Providers AWS
1

Hello everyone! I’m using Terraform to create a simple Application Load Balancer (ALB), but I keep encountering an error when running terraform apply. The error message seems to concatenate the ARN of the ELB Listener with the ARN of the AWS ACM Certificate, which I find strange. I’ve searched my entire project for any incorrect variable usage but couldn’t find any issues. I’m hoping someone can help guide me through this problem.

Here’s the error message I’m getting:

Error: reading ELB (Elastic Load Balancing) Listener Certificate (arn:aws:elasticloadbalancing:us-east-1:{id}:listener/app/my-lb/###############/###############_arn:aws:acm:us-east-1:############:certificate/####################################): ListenerNotFound: One or more listeners not found

And here’s a simplified version of my Terraform code:

terraform {
  required_providers {
    archive = {
      source = "hashicorp/archive"
    }
    aws = {
      source  = "hashicorp/aws"
      version = "~> 4.0"
    }
  }
  required_version = ">= 1.4.2"
}

resource "aws_lb" "main" {
  name               = "my-lb"
  load_balancer_type = "application"
  subnets            = [some var]
  security_groups    = [some var]
}
resource "aws_lb_target_group" "main" {
  name   = "tg-main"
  vpc_id = [vpcid]

  port        = 80
  target_type = "ip"
  protocol    = "HTTP"

  health_check {
    healthy_threshold = 3
    interval          = 100
    timeout           = 30
  }

  #depends_on = [var.sh.main_alb]
}
resource "aws_lb_listener" "https" {
  load_balancer_arn = aws_lb.main.arn

  port            = "443"
  protocol        = "HTTPS"
  ssl_policy      = "ELBSecurityPolicy-2016-08"
  certificate_arn = data.terraform_remote_state.global.outputs.certificate_arn

  default_action {
    type             = "forward"
    target_group_arn = aws_lb_target_group.tg-main.arn
  }
}

I’d really appreciate any guidance or suggestions to help me understand and resolve this issue. Thank you!
