Upload image with twitter lite - node.js

Question

I'm using twitter-lite library and I want to twit an image with text.
I'm able to twit only text, but My goal is twit with text and image.
At the moment I'm trying to use a static image like:
const fs = require("fs")
const imageData = fs.readFileSync("./public/images/watermark_update_idea.png")
const mediaUploadResponse = await client.post('statuses/upload', {
media:imageData,
}).catch(err => {
console.error(err);
});
But I get that error:
{
_headers: Headers {
[Symbol(map)]: [Object: null prototype] {
'cache-control': [Array],
connection: [Array],
'content-encoding': [Array],
'content-length': [Array],
'content-type': [Array],
date: [Array],
server: [Array],
'set-cookie': [Array],
'strict-transport-security': [Array],
'x-connection-hash': [Array],
'x-response-time': [Array],
'x-tsa-request-body-time': [Array]
}
},
errors: [ { message: 'Sorry, that page does not exist', code: 34 } ]
}
My main goal is to twit with buffer, But I get the same error.
I tried to replicate this test but without lucky.

Potentially two issues here:
Use different subdomains for uploading an image and for posting a tweet:
const Twitter = require("twitter-lite");
const client = Twitter({/* auth data */});
const upload = Twitter({/* auth data */, subdomain: "upload"});
You have to convert your image content to a base64 string:
const imageData = fs.readFileSync("./public/images/watermark_update_idea.png");
const { media_id_string } = await upload.post('media/upload', {
media: imageData.toString("base64")
});
