ValueError: No JSON object could be decoded after solving CAPTCHA

Getting "no JSON object could be decoded" on signin, using aws-google-auth 1.5. My account has a few two-factor options, including u2f, Google prompt, and authenticator (TOTP). I get a prompt to solve a captcha. If I fail to solve it, I get a message that says "Invalid captcha." If I solve it correctly, I get this output with debug enabled:
