Unable to create a pool under a batch account with 'IP address provisioning type' set to 'NoPublicIPAddresses' [Python SDK]'

Hi,

Need help on Pool creation using Python SDK. I have a virtual network and also a subnet in my Azure account. I'm trying to create a pool under an existing batch account.

1. Through Azure Portal:

When I create it through the Azure portal I do not have any issues. The process is smooth and the pool and nodes are created successfully. I set the 'IP address provisioning type' parameter to 'NoPublicIPAddresses' and it asks me to change the 'Node communication Mode' to 'Simplified' and I do it. A IP is now created within the subnet.

2. Through Python SDK:

When I try to do the same settings through Python SDK, everything seems right but I get a dumb error which I feel is unrelated.
This is my pool creation function:

def create_pool(batch_service_client: BatchServiceClient, pool_id: str):
    """
    Creates a pool of compute nodes with the specified OS settings.

    :param batch_service_client: A Batch service client.
    :param str pool_id: An ID for the new pool.
    :param str publisher: Marketplace image publisher
    :param str offer: Marketplace image offer
    :param str sku: Marketplace image sku
    """
    print(f'Creating pool [{pool_id}]...')

    # Create a new pool of Linux compute nodes using an Azure Virtual Machines
    # Marketplace image. For more information about creating pools of Linux
    # nodes, see:
    # https://azure.microsoft.com/documentation/articles/batch-linux-nodes/

    # Define the subnet resource ID
    subnet_resource_id = config.SUBNET_ID
    # Configure the network settings
    network_config = batchmodels.NetworkConfiguration(
        subnet_id=subnet_resource_id,
        public_ip_address_configuration=batchmodels.PublicIPAddressConfiguration(
            provision='noPublicIPAddresses'  # Disable public IP addresses
        )
    )

    new_pool = batchmodels.PoolAddParameter(
        id=pool_id,
        virtual_machine_configuration=batchmodels.VirtualMachineConfiguration(
            image_reference=batchmodels.ImageReference(
                
                publisher="microsoftwindowsserver",
                
                offer="windowsserver",
                
                sku="2022-datacenter-smalldisk",
                version="latest"
            ),
            
            node_agent_sku_id="batch.node.windows amd64"
        ),
        user_accounts=[
            batchmodels.UserAccount(
                name="spot",  
                password="Algo&Qua35",
                elevation_level=batchmodels.ElevationLevel.admin
            )
        ],
        vm_size=config.POOL_VM_SIZE,
        target_dedicated_nodes=config.POOL_NODE_COUNT,
        target_low_priority_nodes=config.POOL_LOW_PRIORITY_NODE_COUNT,
        network_configuration=network_config,
        enable_inter_node_communication=False
    )
    batch_service_client.pool.add(new_pool)

And the error I'm receiving with this is below:

The specified subnet acsys-prod-wvd has PrivateLinkServiceNetworkPolicies or PrivateEndpointNetworkPolicies enabled, please disable them to provision NoPublicAddresses Pool

But the annoying part here is that when I look at the subnet's setting in the azure portal for 'Private Endpoint Network Policies', the value is definitely 'DISABLED'.

If someone could through some light on this, I would be very grateful! Thanks in advance!
