Boundary terraform aws example not working

Boundary
4

I have this main.tf file as below, and hitting the LB address which I wiped out, gives the Boundary UI from my first question (meaning that Boundary is properly set, I suppose?). However, when trying to create any boundary resources with terraform, I get the error of 404 resource not found error. I’m unable to get the idea of which resource terraform is unable to find.

Any solutions?

terraform {
  required_providers {
    boundary = {
      source  = "hashicorp/boundary"
      version = "0.1.0"
    }
  }
}

provider "boundary" {
  addr             = "http://boundary-controller-nlb-<MYHASH>.elb.ap-northeast-1.amazonaws.com:9200"
	auth_method_id = "ampw_1234567890"
	password_auth_method_login_name = "infra"
	password_auth_method_password = "infra"
}
