Error: Offset is out of bounds

Hello.
I have all files, run WebTorrent (client.add) and get error:

fs.js:620 Uncaught Error: Offset is out of bounds
    fs.read @ fs.js:620
    onread  @ C:\Projects\launcher\src\main_app\node_modules\random-access-file\index.js:84
    wrapper @ fs.js:614

---

Note:
My server not working, torrent can't download. Screenshot from uTorrent:

Providing the code reproducing that problem should help ;)

It reproducing with webtorrent-cli:

D:\downloads>webtorrent http://example.com/my.torrent 

UNEXPECTED ERROR: If this is a bug in WebTorrent, report it!

For some files i get RangeError: Length extends beyond buffer on the same line.

How did you create that torrent ? Do you have an example of such torrent ? (without copyrighted content)

I think problem not in .torrent. May be problem in file: LifeRace.zip

D:\LifeRace Launcher\main_app\resources\app.asar\node_modules\random-access-file\index.js:84 ..\downloads\LifeRace\LifeRace\Saved\Logs\LifeRace.log RangeError: Length extends beyond buffer(…)
onread @ D:\LifeRace Launcher\main_app\resources\app.asar\node_modules\random-access-file\index.js:84

If we can't reproduce your problem, it's harder to fix it ;)

[green13]

I understand and fully agree, but don't know how reproduce error. I attached file from error, but it looks normal.

[rom1504]

LifeRace.log is the file contained in your torrent ?

Does that error happen in every torrent for you ? If not it looks like the problem is in that torrent.

[green13]

Yes, LifeRace.log contained in my torrent.

Not in every torrent. Yes, it's problem that torrent, but it's not the problem for uTorrent as an example.

For generate torrent I use create-torrent.

@green13 Can you share the code or command line arguments you used to create the torrent?

[green13]

create-torrent: 3.22.0

var fs = require('fs');
var createTorrent = require('create-torrent');
var config = require('./config');
var path = require("path");


function create(folder, name, cb) {
    var opts = {
        name: name,                         // name of the torrent (default = basename of `path`)
        comment: 'no',                      // free-form textual comments of the author
        createdBy: 'SuperApp',              // name and version of program used to create torrent
        private: false,                     // is this a private .torrent? (default = false)
        announceList: config.announceList   // custom trackers (array of arrays of strings) (see [bep12](http://www.bittorrent.org/beps/bep_0012.html))
    };

    createTorrent(folder, opts, function (err, torrent) {
        if (err) {
            throw err;
        }

        var file_name = name + '.torrent';
        fs.writeFileSync(path.join(config.torrentDir, file_name), torrent);

        if (typeof cb === 'function') {
            cb(file_name);
        }
    });
}

module.exports = create;

Sorry -- it's just really hard to solve this issue without a minimal code example that can reliably reproduce it.

If you can produce a minimal test case that exhibits the issue, I'm happy to look at it in a new issue.
