Unable to get vault secret from namespace

Hi,

I have the following terraform template connecting to a enterprise vault under a namespace.

terraform {
  required_providers {
    vault = "~> 2.12"
  }
}

provider "vault" {
  alias      = "base_namespace"
  address    = var.vault_address
  token      = var.vault_token
  namespace  = var.vault_base_namespace
}

provider "vault" {
  alias = "jenkins_namespace"
  address    = var.vault_address
  token      = var.vault_token
  namespace = var.vault_jenkins_namespace
}

provider "vault" {
  alias = "child_namespace"
  address    = var.vault_address
  token      = var.vault_token
  namespace = trimsuffix(vault_namespace.child_namespace.id, "/")
}

resource "vault_namespace" "child_namespace" {
  provider = vault.base_namespace
  path = var.vault_child_namespace
}

data "vault_generic_secret" "jenkins_read" {
  provider = vault.jenkins_namespace
  path = join("/", [ var.kvv2_jenkins_secret_path, "robotconfig" ])
}

data "vault_generic_secret" "k8s_config_3" {
  provider = vault.child_namespace
  path = join("/", [ var.kvv2_secret_path, "config3" ])
}

resource "local_file" "robotK8sconfig_vault" {
    filename = "robotk8_vault_read_new.kubeconfig"
    sensitive_content  = data.vault_generic_secret.k8s_config_3.data.config
    file_permission = "644"
}

resource "local_file" "robotK8sconfig_jenkins_vault" {
    filename = "jenkins_robotk8_vault_read.kubeconfig"
    sensitive_content  = data.vault_generic_secret.jenkins_read.data.config
    file_permission = "644"
}

I get the following error when trying to read from another space

Error: no secret found at "project1/robotconfig"

  on main.tf line 66, in data "vault_generic_secret" "jenkins_read":
  66: data "vault_generic_secret" "jenkins_read" {

The structure is as follows for the sub namespace

myrootnamespace
robotkubeconfigs
jenkins

I am trying to read a secret from Jenkins space with data “vault_generic_secret” . Am i missing something or is that not possible ? I am trying to centralize some common secrets in a global space that can be reused.
