Null error on azure_mgmt_network network_watcher verefy_ip_flow

Hello,

While trying to verify an ip flow using a network watcher, using azure_mgmt_network::package_2021_08::network_watchers verify_ip_flow, I get the following error:

Error: invalid type: null, expected struct VerificationIpFlowResult at line 1 column 4

If I put wrong values in the parameters it fails normaly with the error response from the Azure API.

I have tested the input values on the Azure Portal and it works normally.

Code to reproduce:

Parameters :

let params = VerificationIpFlowParameters {
        target_resource_id: vm_resource_id,
        direction: azure_mgmt_network::models::Direction::Inbound,
        protocol: azure_mgmt_network::models::verification_ip_flow_parameters::Protocol::Tcp,
        local_port: "3389".to_string(),
        remote_port: "5000".to_string(),
        local_ip_address: primary_ip_configuration_private_ip_address.clone(),
        remote_ip_address: "...".to_string(),
        target_nic_resource_id: Some(primary_nic_resource_id),
    };

Parameters output:

Jun 26 12:25:12.309 DEBG VerificationIpFlowParameters {
    target_resource_id: "/…",
    direction: Inbound,
    protocol: Tcp,
    local_port: "3389",
    remote_port: "5000",
    local_ip_address: "…",
    remote_ip_address: "…",
    target_nic_resource_id: Some(
        "/… ",
    ),
}

verify_ip_flow call:

let ip_flow_verify = nw_client
        .verify_ip_flow(
            nw_resource_group_name,
            nw_name,
            parameters,
            subscription_id,
        )
        .await?;
