TypeError: options argument must be an object

var unoconv = require('unoconv');
unoconv.convert('1.docx', 'pdf', function (err, result) {
// result is returned as a Buffer
fs.writeFile('converted.pdf', result);
});

below error:

child_process.js:961
throw new TypeError('options argument must be an object');

The issue is with childProcess.spawn. Using node 0.10.36 should fix your issue. If you can't use an older version try using childProcess.exec(bin, function (err, stdout, stderr) { });

It seems like .spawn has changed slightly and no longer has the option for a callback. if you remove the callback function from the unoconv.convert function so it looks something like this:

child = childProcess.spawn(bin, args);

child.stdout.on('data', function (data) {
    stdout.push(data);
});

child.stderr.on('data', function (data) {
    stderr.push(data);
});

child.on('exit', function () {
    if (stderr.length) {
        return callback(new Error(Buffer.concat(stderr).toString()));
    }

It worked for me!

aeastes is correct. I created a new version of this library a few days ago that uses the new version of childProcess.spawn. You can check it out here: https://github.com/HAASLEWER/unoconv2 and https://www.npmjs.com/package/unoconv2 on npm.
