AzureFunctions binding to SendGrid

Question

Trying to figure out how to use SendGrid from an azure function. Not much docs to find, but this is what I've tried:

#r "SendGrid"
using SendGrid.Helpers.Mail;
using System;

public static void Run(string myQueueItem, out Mail message, TraceWriter log)
{
    log.Info($"C# Queue trigger function processed: {myQueueItem}");
    message=new Mail();
}

I've hardcoded to, from, subject and body, together with api key in the integrate output section. This is my function.json:

{
"bindings": [
{
  "name": "myQueueItem",
  "type": "queueTrigger",
  "direction": "in",
  "queueName": "send-email-request",
  "connection": "myStorage"
},
{
  "type": "sendGrid",
  "name": "message",
  "apiKey": "SG.xxxxxxxxxxx",
  "direction": "out",
  "to": "[email protected]",
  "from": "[email protected]",
  "subject": "hardcoded",
  "text": "test213"
}
],
"disabled": false
}

I get the following error:

Function ($SendEmailOnQueueTriggered) Error: Microsoft.Azure.WebJobs.Host: Error indexing method 'Functions.SendEmailOnQueueTriggered'. Microsoft.Azure.WebJobs.Host: 'SG.xxxxxx' does not resolve to a value.
Session Id: 9426f2d7e4374c7ba7e0612ea5dc1814

I've granted the Apikey full access in SendGrid. Any ideas what I've missed?

The ApiKey field is not the actual ApiKey, it should instead be the name of an AppSettings key defined in the "functions app settings".
