AttributeError: 'int' object has no attribute 'post' : unable to get new username

[jcklpe]

Hi I had amby installed on my self hosted linux media cloud server a couple of years ago and I just moved to a new apartment and decided to try and get amby working on it again. 

I have managed to install it and also get it added to PATH etc but I'm running into a new issue. 

When I try to run the amby command it asks me if I want to create a new username. I confirm Y and then it tells me to hi the Bridge button and press Return. I do this and get the following error message:

```
└─➤ amby 192.168.1.140 1 
No username specified, do you want to create one now? [Y/n]: Y
Press the Bridge button, then press Return:
