Revolt API: How to upload user avatar

[DezyNation]

The official API documentation has mentioned a PATCH request to update the user. But I don't know how to upload the user's avatar.
The documentation asks for an attachment ID in the avatar field but how do we generate that attachment ID? Is there any API available to upload files through autumn?

You can generate any attachment ID if you upload a formdata to autumn. Example using Node.js:

const AUTUMN = 'https://autumn.revolt.chat'
async function uploadFile(tag, buf){
    const formData = new FormData();
    formData.set("file", new Blob([buf]));
    const res = await fetch(`${AUTUMN}/${tag}`, {
        method: 'POST',
        body: formData,
    }).then(res=>res.json());
    return res.id
}
const file = fs.readFileSync('bun.gif');
uploadFile('avatars', file)
    .then(id=>console.log(`Attachment ID is ${id}`))
    .catch(e=>console.error(e));

Edit: ID is generated but GET requests using those IDs seem to fail 🤔
