I have this piece of Terraform code to run a cli bash script to configure a cluster for me, but Terraform will not run the script. The script runs fine, with no errors outside of Terraform.

The Error I am getting is:

│ Error: local-exec provisioner error
│
│   with null_resource.aks_configure,
│   on configure_cluster.tf line 2, in resource "null_resource" "aks_configure":
│    2:   provisioner "local-exec" {
│
│ Error running command './setupcluster.sh -r R21Kubernetes-newprodenveu -l francecentral -c R21KubernetesCluster-newprodenveu -e [email protected] -d argocdnewprodenveu.reporting21.com': exec: "/bin/bash":     
│ executable file not found in %PATH%. Output:
╵

I have tried running this in PowerShell WSL and GitBash. Both give out the same error

Terraform Code:

resource "null_resource" "aks_configure" {
  provisioner "local-exec" {
    command = "${path.module}/setupcluster.sh -r ${local.rg_name} -l ${local.location_for_bash_script} -c ${local.kubernetesclustername} -e ${local.letsencryptemail} -d ${local.fulldnsname}"
    interpreter = ["/bin/bash", "-c" ]
  }
  depends_on = [azurerm_kubernetes_cluster.r21_new_prod_kubernetes, azurerm_resource_group.r21_new_prod_rg  ]
  
}

Folder structure:

The folder structure is below it’s basically one flat folder with everything in it, including the script.
