Issues with Throw errors

[tagyoureit]

Hi,
I've run into a couple of situations where your module Throws an error, but there is no way to catch it in my application. For example,

uncaught exception! Error: type voucher_com_udemy_tv-auth has more than 20 characters

and

It would be great if these errors (and all errors) were emitted to a browser.on('error', function...) event. It would be hard to officially include this module in my code when it causes an error to exit the nodejs process.

thanks!

I fixed these two errors but I wasn't able to push because this repo is giving me a 403. I also can't officially use this module because of guaranteed error messages every time a service has a length longer than 20.

If I understand correctly, you have made some changes to this modules code but havent been able to create a pull request because of 403?

Correct, I've tried with SSH & HTTPS. Maybe I don't have permission to push? I didn't add error emitting or anything, I just removed MAX_STRING from service_type.js along with its references, because I don't see how checking it adds any value, especially when the Error can't be caught.
