Question

Is it possible to have AutoComplete enabled, but still take manual control over it in some functions?

In general, I'm fine with having AutoComplete to true, but I have some long-running functions that can run for longer than the lock duration, so I want to take explicit control of the message. Currently, I defer the message before I begin the actual work, and when I'm done, I retrieve the deferred message and complete it. This works, but I get an error after the message at the end of my function:

[08/06/2020 07:42:35] Executed 'MyFunction' (Succeeded, Id=fbd1d739-1b77-4ce3-99c7-cbae8cfae62b)
[08/06/2020 07:42:41] Message processing error (Action=Complete, ClientId=MessageReceiver3my-queue, EntityPath=my-queue, Endpoint=my-sb-namespace.servicebus.windows.net)
[08/06/2020 07:42:41] Microsoft.Azure.ServiceBus: The lock supplied is invalid. Either the lock expired, or the message has already been removed from the queue, or was received by a different receiver instance.

I think this is because the function host tries to complete the message, which has already been completed.

Is it possible to disable AutoComplete for a specific function?

Hi @thomaslevesque , Have you tried adding the property in your main function code like below:

var options = new SessionHandlerOptions { AutoComplete = false, MessageWaitTimeout = TimeSpan.FromSeconds(3) };

Usually the property is added in host.json like below:

"SessionHandlerOptions": { "autoComplete": false }

But if my understanding is correct, you are looking for a solution for individual function. Please try adding it in your main function.cs and let us know if it works for you.

I am.

Please try adding it in your main function.cs and let us know if it works for you.

I don't understand what you mean... I'm not using sessions.

Where exactly are you including AutoComplete in your code?

Usually added in Host.json, where AutoComplete uses anther setting. Are you talking about any other functionality, could you paste a link for reference.

{ "version": "2.0", "extensions": { "serviceBus": { "SessionHandlerOptions": { "autoComplete": false } } } } }

[thomaslevesque]

On MessageHandlerOptions, not SessionHandlerOptions. But as mentioned in my original post, I don't want to disable AutoComplete globally.

[v-anvari]

Hi @thomaslevesque , In Host settings , we have the option of setting the Autocomplete only globally for now.

Tagging @alrod, for more inputs here. Is it possible to set the AutoComplete for a single function? Can we add this as a feature request?

I think the ask here is the same as in https://github.com/Azure/azure-functions-servicebus-extension/issues/138? I.e., to make the existing host level MessageHandlerOptions configurable per function as well?

[thomaslevesque]

@mathewc yes, exactly

Hi @v-bbalaiagar, @alrod, @v-anvari Quick question on the way to set this autocomplete: false for just one specific azure function and not affect all azure functions running on the function app ? Reason for asking is, what's specified here : https://github.com/Azure/azure-functions-servicebus-extension/issues/138 doesn't seem to work. Can you please share details on how this can be addressed ?
