Application gateway: properties.redirectConfiguration.properties check

[Dylan-Prins]

Description of the issue

I think there should be a check on properties as well:

Rule 'Azure.AppGw.UseHTTPS' -Ref 'AZR-000059' -Type 'Microsoft.Network/applicationGateways' -Tag @{ release = 'GA'; ruleSet = '2021_09'; } {
    $listeners = @($TargetObject.properties.httpListeners | Where-Object { $_.properties.protocol -eq 'http' });
    $requestRoutingRules = @($TargetObject.properties.requestRoutingRules);
    if ($listeners.Length -eq 0 -or $requestRoutingRules.Length -eq 0) {
        return $Assert.Pass();
    }
    foreach ($requestRoutingRule in $requestRoutingRules) {
        $listener = $listeners | Where-Object { $_.name -eq $requestRoutingRule.properties.httpListener.id.Split('/')[-1] };
        if ($Null -eq $listener) {
            $Assert.Pass();
        }
        else {
            $Assert.HasFieldValue($requestRoutingRule, 'properties.redirectConfiguration.id');
        }
        elseif {
            $Assert.HasFieldValue($requestRoutingRule, 'properties.redirectConfiguration.properties');
        }
    }
}

Module in use and version:

• Module: PSRule.Rules.Azure
• Version: [e.g. 1.17.1]

@Dylan-Prins Thanks for reporting the issue.

@Dylan-Prins Are you able to provide an example of the configuration that specifies properties.redirectConfiguration.properties.

From what I can find, properties.redirectConfiguration.properties might be a runtime property that doesn't exist in infrastructure as code but properties.redirectConfiguration.id must always exist regardless if it has been set via infrastructure as code or from an export.

But happy to be corrected.
