azure function servicebustrigger keeps getting (ServiceTimeout)

Question

hi,

We created an isolated function, locally it works but after deploying to azure it does not.

The network on ServiceBus and Function are public as to eliminate any network problems.

looking into kudu logs we see:

Message processing error (Action=Receive, EntityPath=queuemes, Endpoint=myappservicebusdev.servicebus.windows.net)

Azure.Messaging.ServiceBus.ServiceBusException : The operation did not complete within the allocated time 00:01:00 for object tls15. (ServiceTimeout). For troubleshooting information, see https://aka.ms/azsdk/net/servicebus/exceptions/troubleshoot. ---> System.TimeoutException : The operation did not complete within the allocated time 00:01:00 for object tls15.

a different time looking in log stream it shows:

2024-09-29T08:59:55Z   [Verbose]   Request successfully matched the route with name '' and template 'admin/warmup'
2024-09-29T09:01:18Z   [Information]   Message processing error (Action=Receive, EntityPath=
queuemes, Endpoint=myappservicebusdev.servicebus.windows.net)

the function code:

    [FunctionName("FunctionQueue1")]
    public void Run([ServiceBusTrigger("queuemes", Connection = "ServiceBusConnectionString")] string myQueueItem, ILogger log)
    {
        log.LogInformation($"FunctionQueue1, C# ServiceBus queue trigger function processed message: {myQueueItem}");
    }

my startup.cs file:

   class Startup : FunctionsStartup
   {
       public override void ConfigureAppConfiguration(IFunctionsConfigurationBuilder builder)
       {
       }
       public override void Configure(IFunctionsHostBuilder builder)
       {
       }
   }

any help on what am i doing wrong would be greatly appreciated...

I'm at this for over a week

@51062596 Thanks for reaching out. The error message you are seeing indicates that the Service Bus trigger was unable to establish a connection or link to the Service Bus service. This can happen due to network issues or other transient errors that are common in network communication.

However, if you are not experiencing any interruptions to your message processing, you can safely ignore this error message. The Service Bus client used by the trigger will continue to retry connecting to the service indefinitely until it is able to establish a connection.

If you are experiencing an impact to throughput or messages not flowing consistently, you may need to investigate the issue further please open an Azure support request if the issue persists. If you don't have a support plan, please let me know.
