无法使用 Powewshell 创建 AWS ClientVPNEndPoint

问：

我想在 Windows 10 专业版上使用 Powershell 模块 AWSPowerShell.NetCore 版本 4.1.385 创建 ClientVPNEndPoint。

当我运行这个：

    $serverCertificat = Get-ACMCertificateList | where-object { $_.DomainName -eq "server" } 
    $clientCertificat = Get-ACMCertificateList | where-object { $_.DomainName -eq "client1.domain.tld" } 

    $Authentication = new-object Amazon.EC2.Model.ClientVpnAuthenticationRequest
    $Authentication.Type = Amazon.EC2.ClientVpnAuthenticationType.CertificateAuthentication
    $Authentication.MutualAuthentication = new-object Amazon.EC2.Model.CertificateAuthenticationRequest
    $Authentication.MutualAuthentication.ClientRootCertificateChainArn = $clientCertificat.CertificateArn
    
    New-EC2ClientVpnEndpoint -ClientCidrBlock "10.0.0.0/22" `
                            -ServerCertificateArn $serverCertificat.CertificateArn `
                            -AuthenticationOption @($Authentication) `
                            -DnsServer @("172.31.43.131","172.31.30.194") `
                            -vpcid (Get-EC2VPC).VpcId `
                            -ConnectionLogOptions_Enabled $false

...我收到以下错误

Amazon.EC2.ClientVpnAuthenticationType.CertificateAuthentication:

注2：我已经检查了PS模块dll，更具体地说，在没有任何帮助的情况下检查了Amazon.EC2.ClientVpnAuthenticationType
