Azure – Error executing Get-AzFirewallPolicy command for a specific firewall policy

I am trying to list azure firewall policies using Get-AzFirewallPolicy command, but running into mapping error when trying to obtain details of one of the firewall policies.

Following is the command execution:

Get-AzFirewallPolicy -Name "FirewallPolicy_AzureFirewall_EU_NonProd" -ResourceGroupName "RG-Firewalls-NonProd"

Following is the error message:

Get-AzFirewallPolicy : Error mapping types.
Mapping types:
FirewallPolicy -> PSAzureFirewallPolicy
Microsoft.Azure.Management.Network.Models.FirewallPolicy -> Microsoft.Azure.Commands.Network.Models.PSAzureFirewallPolicy
Type Map configuration:
FirewallPolicy -> PSAzureFirewallPolicy
Microsoft.Azure.Management.Network.Models.FirewallPolicy -> Microsoft.Azure.Commands.Network.Models.PSAzureFirewallPolicy
Property:
ThreatIntelWhitelist
At line:1 char:1
+ Get-AzFirewallPolicy -Name "FirewallPolicy_AzureFirewall_EU_NonProd ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : CloseError: (:) [Get-AzFirewallPolicy], AutoMapperMappingException
    + FullyQualifiedErrorId : Microsoft.Azure.Commands.Network.GetAzureFirewallPolicyCommand

I have tried updating my Az.Network(was 5.x now 7.x version) module, but no luck.

TIA

    can you check these, firstly make sure you are using the latest version of the Azure PowerShell module.

    Update-Module -Name Az -Force

    and verify the API version used by the Get-AzFirewallPolicy command. You can use the -ApiVersion parameter to specify the API version explicitly.

    Get-AzFirewallPolicy -Name "FirewallPolicy_AzureFirewall_EU_NonProd" -ResourceGroupName "RG-Firewalls-NonProd" -ApiVersion '2020-05-01'

    This error related to the mapping of types in the Azure PowerShell module try to use below command and Install-Module -Name Az -Force it will update up to date Azure PowerShell module.

    When I ran this PowerShell command, I got detail list of firewall policy like below:

    $firewallPolicy = Get-AzFirewallPolicy -Name "FWNAME" -ResourceGroupName "RGName"
$firewallPolicy | Format-List *

    Output:
