Send data as a json file with discord.js

Question

I'm trying to send some javascript object (as JSON data in a json file) with a command using discord.js. Yet It's not as easy as sending an image. I tried using AttachmentBuilder (with/without JSON.stringify), with and without the additional data being the name:

const jsonFile = new AttachmentBuilder(JSON.stringify(data), {
    name: embedName + ".json",
  });
message.reply({ content: "Data:", files : [jsonFile]})

But I get this weird error no matter how i put my data:

TypeError: Cannot read properties of undefined (reading 'Symbol(Symbol.asyncIterator)')

You would need to use a buffer to stream the data to the builder. You can do so by using Buffer.from(<target>). You can learn more about buffers here or access the Node.js docs here.

Example using your source:

const jsonFile = new AttachmentBuilder(Buffer.from(JSON.stringify(data)), {
    name: embedName + ".json",
  });
