SwaggerWCF configuration for self hosted WCF library

Question

I'm having some difficulties getting SwaggerWCF to load my documentation page, and I'm not sure why. I get no errors, but I also get no Swagger docs either, just a 404 when I visit http://localhost:8733/docs per the endpoint configuration. What am I doing wrong here? I have everything decorated up, using Framework 4.8. Service works fine and the mex and js endpoints will return data, just no swaggerUI.

Here is my App.Config:

<system.serviceModel>
        <standardEndpoints>
            <webHttpEndpoint>
                <standardEndpoint name="" contentTypeMapper="Microsoft.Samples.WebContentTypeMapper.JsonContentTypeMapper, JsonContentTypeMapper, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
            </webHttpEndpoint>
        </standardEndpoints>
        <services>
            <service name="AutodeskVaultAPI.VaultWorker">
                <endpoint address="" binding="basicHttpBinding" contract="AutodeskVaultAPI.IVaultServices">

                    </identity>
                </endpoint>
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
                <endpoint address="js" behaviorConfiguration="jsonEP" binding="webHttpBinding"
                 name="jsonEP" contract="AutodeskVaultAPI.IVaultServices" />
                <host>
                    <baseAddresses>
                        <add baseAddress="http://localhost:8733/AutodeskVaultAPI/" />
                    </baseAddresses>
                </host>
            </service>
            <service name="SwaggerWcf.SwaggerWcfEndpoint">
                <endpoint address="http://localhost:8733/docs" binding="webHttpBinding" contract="SwaggerWcf.ISwaggerWcfEndpoint" />
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior>
                    <serviceMetadata httpGetEnabled="True" httpsGetEnabled="True" />
                    <serviceDebug includeExceptionDetailInFaults="True" />
                </behavior>
            </serviceBehaviors>
            <endpointBehaviors>
                <behavior name="jsonEP">
                    <webHttp helpEnabled="true" automaticFormatSelectionEnabled="true"/>
                </behavior>
            </endpointBehaviors>
        </behaviors>
    </system.serviceModel>

Here is my service implementation:

You need to check the code written in Global.asax .

protected void Application_Start(object sender, EventArgs e)
{
         // [.......]    
         RouteTable.Routes.Add(new ServiceRoute("api-docs", new WebServiceHostFactory(), typeof(SwaggerWcfEndpoint)));
}

Edit Web.config and add the following in the system.serviceModel block.

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>

Edit Web.config again and add the following in the system.webServer block.

<modules runAllManagedModulesForAllRequests="true"/>

You can refer to the steps provided in the link for details.
