C# BasicDeliverEventArgs not available

[niwrA]

When I setup a trigger to receive the BasicDeliverEventArgs, I get an empty object:

For instance, when I do this:

public void Run(
    [RabbitMQTrigger("queue", ConnectionStringSetting = "RabbitMQConnection")] BasicDeliverEventArgs args)
{

For me I need the reply-to property, which is generated by RabbitMQ when you send a message using the direct-reply method and has a unique id attached to it that I can only find here. So there is no other way for me to solve this issue, rendering azure functions useless for me for this purpose at the moment.

I'm testing this locally. If I use this, as I do in another trigger where I don't need reply-to, I do get the message correctly:

public void Run(
    [RabbitMQTrigger("otherqueue", ConnectionStringSetting = "RabbitMQConnection")] string message)
{

Documentation around the web suggested that this method should work and I couldn't find any other method to get the replyto property. Can anyone help?

Hi @niwrA, we have tested the scenario you mentioned in local setup using samples in the repo and were able to receive a populated BasicDeliverEventArgs object. Would you mind sharing more details about your function, settings etc to let us help you?

Regarding the second part of your query, you can access the reply-to property in your function using BasicDeliverEventArgs.BasicProperties.ReplyTo.

i also have this problem with and only with the rabbitmq trigger in durable functions dotnet-isolated

this is to report that if you inject FunctionContext as per the attached you may find the items you're looking for in BasicDeliverEventArgs

i'm about to try this workaround out now
