Azure function documentdb out parameters error

How do I use docuementdb binding with azure function http binding:

using System.Net;

public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, out object locationDocument, TraceWriter log){
    log.Info("C# HTTP trigger function processed a request.");
    var data = await req.Content.ReadAsStringAsync();

    return req.CreateResponse(HttpStatusCode.OK, $"{data}");
}

Getting this error:

error CS1988: Async methods cannot have ref or out parameters

This is not specific to Document DB. If your function is async, and you already used the return value for HTTP output binding, you would need to inject IAsyncCollector<T> for all other output bindings.

See the second example in this answer.
