MassTransit with Azure Functions error: "The lock supplied is invalid. Either the lock expired, or the message has already been removed from the queue."

Hello!

I have an issue when using MassTransit with Azure Functions v1 (.NET Framework 4.6.1). I tried to run a basic Azure Function directly inspired from the sample provided in the project documentation : http://masstransit-project.com/MassTransit/usage/azure-functions.html.

The message is successfuly consumed by the IConsumer, and the Azure Function returns without any problem. However, I get the following error message immediately after the Azure Function execution ends : Microsoft.ServiceBus: The lock supplied is invalid. Either the lock expired, or the message has already been removed from the queue.

It looks like the Azure Functions SDK is expecting the message to still be present in the queue at the end of the function’s execution, in order to remove it. But the message is gone, the BrokeredMessageReceiver has already removed it from the queue by calling BrokeredMessage.CompleteAsync() in its Handle method.

Is there something I’m doing wrong?

Thanks!

SDK and lib versions:

• Azure Functions v1 (.NET Framework 4.6.1)
• Microsoft.NET.Sdk.Functions (1.0.4)
• Newtonsoft.Json (11.0.2)
• MassTransit.WebJobs.ServiceBus (5.1.4)

Sample log

Here is the log of the Azure Function’s execution. You can see that the function succeeds before the error occurs.

This isn’t an issue now, and you need to select auto-confirm or whatever in your function config. Works only in the develop branch at this point until 5.2.1 is released.

Once support is moved to Azure Functions v2, wonder if this will still be an issue.
