Upload video error NOT FOUND

[alexnyde]

Why it returns “error: Not found” when I use the “APPEND” command?

var request = require('request');
var fs = require('fs');

var twitterUpload = new TwitterVideoUpload(oauth);

twitterUpload.uploadFile({
    path: './video.mp4',
    total_bytes: 752333
}, function (media_id) { 
    console.log('Media ID', media_id);
});

The video that I’m using is this: https://video.twimg.com/ext_tw_video/601491637433475073/pu/vid/640x360/DRQCQaiww7XlAYJP.mp4

These are the headers that I’m sending when I use the command “APPEND” (segment_index was 0, but I skipped one step in the debugger and becomes 2):
