EventHubTrigger : connection: Azure IoTHub

Samy 1

Hi,
I tried to configure the EventHubTrigger.

https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-event-iot-trigger?tabs=in-process%2Cfunctionsv2%2Cextensionv5&pivots=programming-language-csharp

Could yo help me to configure the field "Connection" ?

Which field can I put from "Built-in endpoints" in IotHub ?
Endpoint ?
SharedAccessKeyName ?
SharedAccessKey ?
...

Best regards.

Samy

Hello @Samy

We can make use of the EventHub compatible endpoint to make the Azure Function trigger. Below is something which i have used!

Get the Eventhub compatible endpoint address!

Use your IotHub name and the EventHub compatible endpoint.

Sample output showing the triggered events from the Azure Function app!

This is a very straight way to use the built-in endpoint, please comment in the below section if you need further help in this matter!

Thanks for your response and your explanation.
Did you use the last version of Microfost.Azure.WebJobs.Extensions.EventHub ?
If no which version did you used ?

I received this exception in the method
public Task<IListener> CreateListenerAsync(ListenerFactoryContext context)
{
var listenerTask = _createListener(context, _singleDispatch);
return listenerTask;
}

System.ArgumentException: 'The path to an Event Hub may be specified as part of the connection string or as a separate value, but not both. Please verify that your connection string does not have the EntityPath token if you are passing an explicit Event Hub name. (Parameter 'connectionString')'

Hello @Samy ,

I have created a new Azure Function App -->EventHub Triggered-->Add the connectionString-->Run the app.

I haven't used any specific versions of NuGet packages during this testing!

I have used the version 5.0.0

I used the same version of you. I have an error when a start the application.
The application works with the version 4.3.0 and 4.0.0. But when I update I received an exception.

I tried also to update with the last version. In this time, I had another issue.

Could you please do the same and update with the last version ? Just to see if you have the same issue.
My application works in the version 4.3.0 and 4.0.0.
