Receiving a 'Invalid Parameter' SKU error when trying to create a Linux VM Scale Set in Az-CodePudding

I am a beginner learning Terraform and need some advice. I am trying to create a Linux VM Scale Set in Azure using Terraform. I used the code in the Terraform documentation to set the source_image_reference like this:

# Configure the Azure VM scale set
resource "azurerm_linux_virtual_machine_scale_set" "demo-vmss" {
  name = "demo-vmss"
  location = azurerm_resource_group.demo-rg.location
  resource_group_name = azurerm_resource_group.demo-rg.name
  admin_username = "admin-user"
  admin_password = "Password123!"
  instances = 2
  zones = [1,2,3]
  sku = "Standard_B1s"

source_image_reference {
    publisher = "Canonical"
    offer     = "UbuntuServer"
    sku       = "20.04 LTS"
    version   = "latest"
    }

  os_disk {
    caching = "ReadWrite"
    storage_account_type = "Standard_LRS"
  }

  network_interface {
    name = "demo-network-interface"

    ip_configuration {
      name = "vmss-ip-config"
      primary = true
      subnet_id = azurerm_subnet.vm-subnet.id
    }
  }
}

No matter what value I put for the sku or offer in the source_image_reference, I receive this error in PowerShell:

creating Linux Virtual Machine Scale Set: (Name "demo-vmss" / Resource Group "myTFResourceGroup"): 
compute.VirtualMachineScaleSetsClient#CreateOrUpdate: Failure sending request: StatusCode=400 -- Original Error: Code="InvalidParameter" Message="The value of parameter imageReference.offer 
is invalid." Target="imageReference.offer"

Can anyone please suggest what I can do to fix this error and what is causing the problem (so I can learn for future)? This is my first time writing a question here so please let me know if you need me to provide more information. Any help provided will be much appreciated.

The offer and SKUs for Ubuntu changed recently. See the following links for details: https://lnx.azurewebsites.net/ubuntu-new-offers-and-skus-for-azure-vms/amp/

This error may occur in imageReference.offerWhen I try to discover that it is available but goes by a different name and is in fact sort of hidden, use below as same

source_image_reference {
    publisher = "Canonical"
    offer     = "0001-com-ubuntu-server-focal"
    sku       = "20_04-lts-gen2"```
    version   = "latest"
    }
