[BUG] Azure.Messaging.EventHubs: System.InvalidOperationException: 'Operation is not valid due to the current state of the object.'

Describe the bug Executing the following code with version 5.2.0 of Azure.Messaging.EventHubs results in an exception:

var producer = new EventHubProducerClient(ConfigStuff.connectionString, ConfigStuff.eventHubName);
var partitions = await producer.GetPartitionIdsAsync();

Exception:

System.InvalidOperationException: Operation is not valid due to the current state of the object.

This exception only occurs for .NET 5.0

Expected behavior I would expect this code to work without throwing an error

Actual behavior (include Exception or Stack Trace)

Stacktrace:

System.InvalidOperationException: Operation is not valid due to the current state of the object.

I saw some previous issues regarding this were already closed, but the bug doesn’t seem to be resolved: https://github.com/Azure/azure-sdk-for-net/issues/14068 https://github.com/Azure/azure-sdk-for-net/issues/13899

Manually installing the latest version of Microsoft.Azure.Amqp resolves this issue:

Install-Package Microsoft.Azure.Amqp

@jsquire I have also the error. Created a EventHub Trigger for IotHub from template in VS2022

#    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.EventHubs" Version="4.2.0" />
#    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.0.1" />
using IoTHubTrigger = Microsoft.Azure.WebJobs.EventHubTriggerAttribute;

using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Host;
using Microsoft.Azure.EventHubs;
using System.Text;
using System.Net.Http;
using Microsoft.Extensions.Logging;

namespace FunctionApp1
{
    public class Function1
    {
        private static HttpClient client = new HttpClient();
        
        [FunctionName("Function1")]
        public void Run([IoTHubTrigger("messages/events", Connection = "EventHubConnectionString", ConsumerGroup = "iot-euw-iotdatastorage-prod-func")]EventData message, ILogger log)
        {
            log.LogInformation($"C# IoT Hub trigger function processed a message: {Encoding.UTF8.GetString(message.Body.Array)}");
        }
    }
}

The error output ist:

after adding the reference to <PackageReference Include="Microsoft.Azure.Amqp" Version="2.5.8" /> explizit as @devedse said, it works now
