Serilog Date not being appended to log filename

Question

I have Serilog setup and logging in my application, however the date is not being appended to filename. The log file gets created as Log-.log instead of Log-20220302.log. Relevant code is shown below. The nuget package Serilog.Sinks.File has been installed. Any ideas why?

public override void Bind(ref IContainer container)
    {
        container.Register(
            () => new LoggerFactory(
                new ILoggerProvider[]
                {
                    new SerilogLoggerProvider(
                        new LoggerConfiguration()
                            .ReadFrom.AppSettings()
                            .Enrich.FromLogContext()
                            .CreateLogger()),
                    new DebugLoggerProvider(),
                }).AddSerilog(),
            DependencyScope.Singleton);

        container.Register(typeof(ILogger<>), typeof(Logger<>), DependencyScope.Singleton);
    }

Web.config

<appSettings>
    <add key="serilog:using:File" value="Serilog.Sinks.File" />
    <add key="serilog:write-to:File.path" value="C:\logs\Log-.log" />
    <add key="serilog:write-to:File.rollingInterval" value="Day" />
</appSettings>

Notice the double period in the file name. Example output apilog.20220114.log

// API appsettings.json

        },
