User will not be saved: One attribute is not valid, would you mind to take a look at them?

[Maxeeezy]

I cloned the repo and got set up the quickstart application as described in the manual. However, when I put in data in the register view it will not authenticate me. It alerts me to check the console, which says 'One attribute is not valid, would you mind take a look at them?'.
I tried several combinations for the inputs, including the ones from another of your documentations:

name: Max
email: new_user@email.com
country_code: 49
cellphone: 405-342-5699

It did not work. When I put the authy variable that gets the response from your API, it gives me an empty object.

Do you have an idea what the issue might be here?

Furthermore, it would be more helpful if the error message would cover more in depth explanation, what the response actually says.

I found out the application did not have access to the yml. So it was due to the missing API key that the response sent an empty object back. I had to require 'authy' in the users_controller, as well as

Authy.api_key = ENV['AUTHY_KEY'] Authy.api_uri = 'https://api.authy.com/'

Furthermore dotenv must first be installed, to check the .env.
