Seems like the code it's having trouble with is this the last part of this:

resource "aws_db_instance" "db" {
   for_each = { for db in var.db_instances : db.identifier => db }
 
   identifier              = "${var.environment}-${each.value.identifier}"
   instance_class          = each.value.size
   engine                  = each.value.engine
   engine_version          = each.value.engine_version
   allocated_storage       = each.value.storage_gb
   max_allocated_storage   = each.value.max_storage_gb
   storage_type            = "gp3"
   storage_encrypted       = true
   kms_key_id              = var.kms_key_rds_arn
   multi_az                = false
   deletion_protection     = false
   skip_final_snapshot     = true
   apply_immediately       = true

   # Credentials pulled from Secrets Manager
   username = each.value.username
   password = random_password.db_password[each.key].result
