Azure custom script extension timeout when deploying with Terraform-CodePudding

When deploying a custom script extension for a VM in Azure, it times out after 15 minutes. The timeout block is set to 2hrs. I cannot figure out why it keeps timing out. Could anyone point me in the right direction please? Thanks.

In Azure, each resource will take a particular amount of time for provisioning. For Virtual Network Gateway's/ Virtual machines, timeout is up to 2 hours as mentioned in terraform timeouts.

Therefore, the timeout block we provide for any virtual machine has to be less than two hours (2h).

I tried creating a replica for azure vm extension resource by using below terraform code and it deployed successfully.

timeout block:

timeouts {
    create =  "1h30m"
    delete =  "20m"
  }

azure_VM_extension:

resource "azurerm_virtual_machine_extension" "xxxxx" {
  name                 = "xxxxname"
  virtual_machine_id   = azurerm_virtual_machine.example.id
  publisher            = "Microsoft.Azure.Extensions"
  type                 = "CustomScript"
  type_handler_version = "2.0"
   settings = <<SETTINGS
 {
  "commandToExecute": "hostname && uptime"
 }
SETTINGS
  tags = {
    environment = "Production"
  }
timeouts {
    create =  "1h30m"
    delete =  "20m"
  }
}

Created a virtual machine by adding required configurations under resource group.

You can upgrade status if you want to use extensions.

I resolved the issue by changing the type_handler_version to 1.9.
