"complete" event triggers twice

[crtag]

In this simple scenario:

restler.get(url)
        .on(
            'complete',
            function(data, resO) {
                console.log(data);
            }
        );

console is used twice, first time with error, which is irrelevant and was tested against possible server side issue

{ [Error: Parse Error] bytesParsed: 246, code: 'HPE_INVALID_CONSTANT' }

and null on the second time

null

which is not correct as well.
