Two different events on one trigger

[ashamrai]

As inheritor of https://github.com/Azure/Azure-Functions/issues/2310

Runtime version: ~4 Os: windows Hosting plan: consumption Language: java Trigger: Event Hub

When we receive "Did not find any initialized language workers", we expect retrying of failed function.

Example:

This is traces of the failed execution:

and we see the retries (line 2 and 3):

However, the first retry receives:

The second retry receives:

So... two executions with the same partition, offset, sequence number and enqueue time receive two different events.

Then I`ve tried to read this event through this simple code:

       var consumer = new EventHubConsumerClient(consumerGroup, connectionString, eventHubName);

        EventPosition eventPosition = EventPosition.FromSequenceNumber(9916);            

        await foreach (var ev in consumer.ReadEventsFromPartitionAsync("6", eventPosition))
        {

            ReadOnlyMemory<byte> eventBodyBytess = ev.Data.EventBody.ToMemory();

            var bodys = eventBodyBytess.ToArray();
            var messages = Encoding.UTF8.GetString(bodys);
            Console.WriteLine("{0}", messages);

            return;
        }

• When I use EventPosition eventPosition = EventPosition.FromSequenceNumber(9916); I receive: {{"traceId":"6324e22b-cef2-440a-a4ee-f0dc66c5752a","timestamp":"2022-12-07T07:08:09.000" ... as in the first retry

• When I use EventPosition eventPosition = EventPosition.FromOffset(98805874928); I receive: {{"traceId":"6324e22b-cef2-440a-a4ee-f0dc66c5752a","timestamp":"2022-12-07T07:08:09.000" ... as in the first retry

• But when I use EventPosition eventPosition = EventPosition.FromEnqueuedTime(new DateTimeOffset(DateTime.Parse("2022-12-07T13:08:42.5270000Z"))); I receive: {{"traceId":"21d31271-d42b-4840-961e-8175c50de7b2","timestamp":"2022-12-07T06:45:30.000" ... as in the second retry

So... Why do two different executions (with the same trigger) return different result?

@bhagyshricompany our configuration:

{
    "version": "2.0",
    "extensionBundle": {

@sidkri pls comment

@ashamrai Ican see function is still runing in problematic version. please go through this link which is updated for fixed. https://github.com/Azure/azure-functions-eventhubs-extension/issues/114

[sidkri]

Thanks @bhagyshricompany for identifying the work around. @ashamrai please upgrade to extensions bundle v4 which uses the latest verison of the Event Hubs extension and SDK that does not have this logging issue: https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-register#extension-bundles Set the extensionBundle.version to "[4.0.0, 5.0.0)". Compile locally to ensure no code changes are needed.

Please close this issue once you have upgraded and no longer have the issue as we are tracking the logging issue via #144
