Azure Queue: Unable to read cloud queue messages. AsString and AsBytes properties are throwing System.ArgumentException

Question

Ok, I have a class intended to manage Azure cloud queue messages, the insertions are working fine:

    public async void Insert(string message)
    {
        await Queue.AddMessageAsync(new CloudQueueMessage(message));
    }

Note that this Queue is a CloudQueue instance.

This is the message inserted in the storage using the above method

But, while trying to Get or Peek messages, a weird behavior is happening and I can't read anything of the content:

The content of the message is throwing an exception and is being returned as null.

This is the messageCount value.

Here's textually, the method used to retrieve the messages:

    public async Task<List<string>> GetMessages()
    {
        var list = new List<string>();

        await Queue.FetchAttributesAsync();
        int messageCount = Queue.ApproximateMessageCount ?? 0;

        if (messageCount == 0) return list;

        foreach (var msg in await Queue.GetMessagesAsync(messageCount))
        {
            
             list.Add(msg.AsString);
        }

        return list;
    }

EDIT: I checked as pointed in the approved answer and figured out that I was using a deprecated package that seems to work no longer. This library has been split in multiple parts and is deprecated.

I had to use a most recent API and change my code, it's actually easier to use but a certain rework was needed. It's now working, and the way to use the queue in this new version (.NET v12) is documented here.

I believe it's related to wrong (legacy) Nuget Package. I've faced a problem like this recently and it was solved when I've upgraded to the following Packages:

Install-Package Microsoft.Azure.Storage.Common -Version 11.1.7
Install-Package Microsoft.Azure.Storage.Queue -Version 11.1.7
