在IIS中使用wsHttpBinding托管WCF服务时出现问题

我正在尝试使用以下配置托管我的服务

<system.serviceModel>
    <services>
        <service name="Test.MyService" behaviorConfiguration="MyServiceBehavior">
            <!--         Service Endpoints -->
            <endpoint address="MyTestService" binding="wsHttpBinding" bindingConfiguration="WebserviceHttpBinding" contract="Test.IMyService"/>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        </service>
    </services>
    <bindings>
        <wsHttpBinding>
            <binding name="WebserviceHttpBinding">
                <security mode="Message">
                    <message clientCredentialType="UserName" negotiateServiceCredential="false"/>
                </security>
            </binding>
        </wsHttpBinding>
    </bindings>
    <behaviors>
        <serviceBehaviors>
            <behavior name="MyServiceBehavior">
                <serviceCredentials>
                    <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="Test.CredentialValidator, Test"/>
                    <serviceCertificate findValue="RPKey" x509FindType="FindBySubjectName" storeLocation="LocalMachine" storeName="My"/>
                </serviceCredentials>
                <!--           To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
                <serviceMetadata httpGetEnabled="true"/>
                <!--           To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
                <serviceDebug includeExceptionDetailInFaults="true"/>
            </behavior>
        </serviceBehaviors>
    </behaviors>
</system.serviceModel>

当我调试这个服务时，我没有问题。我使用网站在IIS中托管了此服务。当我从IIS浏览此服务时，出现以下异常
