Exception binding parameter 'myEventHubMessage'. Microsoft.Azure.WebJobs.Host: Object reference not set to an instance of an object.

_From @grik001 on July 26, 2018 13:19_

I am following the example in this link:

https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-event-hubs, The first example works and I manage pick up calls from EventHub.

When I try the second example which uses EventData from SB I keep getting the below exception:

**Method:**

```csharp
public static void Run(
[EventHubTrigger("invictus-dev-we-sft-evhb", Connection = "EventHubConnectionAppSetting")] EventData myEventHubMessage,DateTime enqueuedTimeUtc,
Int64 sequenceNumber,string offset,TraceWriter log)
```

**Error:**

```

Start with the Run method signature and the EventHubTrigger/EventData example linked in the report. Reproduce the binding failure and inspect the host's EventData, enqueuedTimeUtc, sequenceNumber, and offset binding paths; done means the documented signature either binds successfully or the documentation clearly reflects the supported parameters.
