Terraform import failure on module

Terraform

Team,
I have an aurora-db that was created manually and now i am trying to import it into terraform.

I created this .tf file and ran terraform plan, which gives me the plan output and it shows it is trying to create the instance.

  source = "terraform-aws-modules/rds-aurora/aws"

  name                                        = "aurora-db-dev"
  engine                                      = "aurora-postgresql"
  engine_mode                                 = "provisioned"
  engine_version                              = "15.4"
  master_username                             = "master"
  storage_encrypted                           = true
  storage_type                                = "aurora-iopt1"
  vpc_id                                      = module.vpc.vpc_id
  db_subnet_group_name                        = aws_db_subnet_group.serverless-v2.name
  db_cluster_parameter_group_name             = aws_rds_cluster_parameter_group.d.name
  db_cluster_db_instance_parameter_group_name = aws_db_parameter_group.d.name
  db_parameter_group_name                     = aws_db_parameter_group.dcp-d.name
  deletion_protection                         = true

  manage_master_user_password = false
  master_password             = random_password.master-v2.result

  serverlessv2_scaling_configuration = {
    min_capacity = var.rds_autoscaling_min_capacity
    max_capacity = var.rds_autoscaling_max_capacity
  }

  instance_class = "db.serverless"
  instances = {
    one = {identifier     = "aurora-db-1"}
    two = {identifier     = "aurora-db-2"}
  }

  security_group_rules = {
    vpc_ingress = {
      cidr_blocks = [var.vpc_cidr]
    }
  }
  # availability_zones = var.rds_azs

  apply_immediately   = true
  monitoring_interval = 10

  # enabled_cloudwatch_logs_exports = ["postgresql"]
  skip_final_snapshot = true
}

plan is:

 # module.cluster-serverless-v2-import.aws_rds_cluster.this[0] will be created
  + resource "aws_rds_cluster" "this" {
      + allocated_storage                     = (known after apply)
      + allow_major_version_upgrade           = false
      + apply_immediately                     = true
      + arn                                   = (known after apply)
      + availability_zones                    = (known after apply)
      + backtrack_window                      = 0
      + backup_retention_period               = (known after apply)
      + ca_certificate_identifier             = (known after apply)
      + ca_certificate_valid_till             = (known after apply)
      + cluster_identifier                    = "aurora-db-dev"

but when i import it

terraform import module.cluster-serverless-v2-import.aws_rds_cluster.this aurora-db-dev

it fails with this output

│ Error: Configuration for import target does not exist
│
│ The configuration for the given import module.cluster-serverless-v2-import.aws_rds_cluster.this does not exist. All target instances must have an
│ associated configuration to be imported.

Trying to understand what is going wrong here. Doing the same steps on a simple EC2 instance (viar resource and not module worked)

Hi,
The module terraform-aws-modules/rds-aurora/aws is using count, so you need to adjust from this:

terraform import module.cluster-serverless-v2-import.aws_rds_cluster.this aurora-db-dev

to this:

terraform import 'module.cluster-serverless-v2-import.aws_rds_cluster.this[0]' aurora-db-dev
