Script compilation failed. for Azure Function App

I have set up Twilio with a webhook to call a Function App. I have the following code in my Function App

using System.Net;

public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log)
{
    log.Info("C# HTTP trigger function processed a request.");
    // dynamic data = await req.Content.ReadAsAsync<object>();
    // lots of commented out code
}

When the function runs the log shows the following error

Exception while executing function: Functions.HttpTriggerCSharp1
Microsoft.Azure.WebJobs.Host.FunctionInvocationException : Exception while executing function: Functions.HttpTriggerCSharp1 ---> Microsoft.CodeAnalysis.Scripting.CompilationErrorException : Script compilation failed.

Is a call to await required? If I un-comment that call I still get the error

It is important that you should not have any compilation errors. Make sure you are returning something using await or response

public static async Task Run(TimerInfo myTimer, TraceWriter log)
{
    log.Info("C# HTTP trigger function processed a request.");
    return req.CreateResponse(HttpStatusCode.OK, $"Current Time : {DateTime.Now}");    
}
