Recurring "Cannot send an empty message" error

Hello, I'm intermittently getting hit with 50006 "Cannot send an empty message" errors in a production environment using discord.js. I can't seem to find any pattern aside from the fact that it occurs when sending attachments, specifically text files I've created server-side. Simply running a command multiple times will sometimes succeed and sometimes fail. Any ideas as to why this could be happening?!

- What's your exact discord.js npm list discord.js and node node -v version? - Not a discord.js issue?

Here is the full error:

DiscordAPIError[50006]: Cannot send an empty message
    at new _DiscordAPIError (./node_modules/@discordjs/rest/dist/index.js:583:9)

}

The code is a bit complex and spans multiple files/functions, but in the end the important part is:

const attachments = [new AttachmentBuilder(Buffer.from(`# Before\n\n${oldContent}\n\n# After\n\n${newContent}`), {
              name: `${newMessage.id}-content-changes.txt`,
              description: `A file containing the content changes from the message ${newMessage.id} at ${Date.now()}`,
          })];

// ...

targetChannel.fetch().then((channel) => channel.send({ embeds: [embed], files: attachments }));

const attachments = [new AttachmentBuilder(Buffer.from(`# Before\n\n${oldContent}\n\n# After\n\n${newContent}`), {
              name: `${newMessage.id}-content-changes.txt`,
              description: `A file containing the content changes from the message ${newMessage.id} at ${Date.now()}`,
          })];

// ...

targetChannel.fetch().then((channel) => channel.send({ embeds: [embed], files: attachments }));

The issue occurs without embeds as well (even if that parameter isn't provided)

Agreed! and this only started happening suddenly without any noticeable cause The production environment also has the same dependency and node versions

Node: v22.4.1 Bun: 1.1.20 (not actually sure if that is the same in production now that I think about it) I've also tested without bufferutil and utf-8-validate, though the issue persisted
