Registration Fails Requiring Captcha but Provides no Captcha URL

[TwilightCitizen]

The title very nearly captures it all. When the register() method of a KikClient is called with pertinent details of an unregistered account (excluding captcha_result), on_register_error of the client's callback fires, indicating that captcha is required. However, no captcha URL is ever provided, essentially rendering the client's register method useless.

Is there some other way to trigger a captcha or obtain a captcha URL for this? Could the result of a captcha from something like a login attempt on another registered account be used, or is the captcha stateful with respect to the type of request?

Captcha tokens (urls) are bound to the username, they cannot be taken from one username and be used to solve for a different account.
There's likely a bug in the captcha parsing / handling in this repo preventing the captcha_url from being provided.

I would enable debug logs and print out the raw response to registration to figure out the problem.
This is the logic:

if data.find('captcha-url'):
