InvalidParameterValue: Capacity value 1 is not valid.

[nicklunt]

Initial terraform apply works great. Then making no changes just running a plan immediately says the min_capacity is going to be changed from 2 -> 1.

 ~ scaling_configuration {
   ~ min_capacity             = 2 -> 1
}

Running the terraform apply then gives this back

╷

I have run terraform destroy, rm -rf .terraform and reapplied but I get the same issue.

I am calling the module with this

module "aurora_pg_db" {
  source = "./modules/terraform-aws-rds-aurora"

  name           = var.aurora_database_name
  engine         = "aurora-postgresql"
  engine_mode  = "serverless"
  autoscaling_enabled    = false
  create_random_password = false
  master_username        = local.db_creds.username
  master_password        = local.db_creds.password
  deletion_protection    = false
  skip_final_snapshot    = true
  vpc_id                 = var.aurora_vpc_id
  subnets                = flatten(var.aurora_subnet_ids)
  allowed_cidr_blocks    = ["0.0.0.0/0"]
}

Provider plugins aws v4.0.0 random v3.1.0

I suspect user error, but can't see how.

FWIW, this is still an issue with serverless Aurora.
