Removing Attachments With UpdateAsync?

[upbeat anvil]

Idea: use UpdateAsync() to remove an embed from a message.
Here's my code that sends the attachment:

await interaction.UpdateAsync(x =>
            {
                x.Embed = null;
                x.Attachments = new[] { new FileAttachment(path: "VerdantRecords.png", fileName: "VerdantRecords.png") };
                x.Components = // Other working stuff

And here's the code that removes the attachment:

await interaction.UpdateAsync(x =>
            {
                x.Embed = // Other working stuff
                x.Attachments = null;
                x.Components = // Other working stuff
            });

The attachment is sent just fine, but when setting x.Attachments to null, it... times out? Errors? Unsure. I tried using a try and catch statement, but there's no thrown exception.

Am I doing something wrong? Am I crazy? Usually setting the Embed, Content, etc., to null works perfectly. I have tried using ModifyOriginalResponseAync as well.

what if you set that to an empty array?

dnet's modify methods are just inconsistent

we should probably review all of those in v4

so they'd work as expected...

Throws the error: Path cannot be null

Side note: updating to another image works just fine

For anyone that stumbles upon this thread, this was mostly fixed in D.NET 3.12.0. In a nutshell, you currently need to use ModifyAsync(), as UpdateAsync() and ModifyOriginalResponseAsync() don't seem to work here.

Working code:

await Context.Interaction.DeferAsync(true);

var interaction = await Context.Interaction.GetOriginalResponseAsync();

await interaction.ModifyAsync(x =>
{
    x.Attachments = null;
    x.Embed = // Stuff
    x.Components = // Stuff
});
