2fa verification problem

[ramimoghrabi]

i am doing the 2fa verification with the authenticator, but receiving error 400 see below some of the output :

invalidResponse(<NSHTTPURLResponse: 0x600001f070a0> { URL: https://i.instagram.com/api/v1/accounts/two_factor_login/ } { Status Code: 400, Headers {
"Alt-Svc" = (
"h3=":443"; ma=3600,h3-29=":443"; ma=3600"
);
"Cache-Control" = (
"private, no-cache, no-store, must-revalidate"
);
"Content-Language" = (
en
);
"Content-Length" = (
123
);
"Content-Type" = (
"application/json; charset=utf-8"
);
Date = (
"Mon, 15 Nov 2021 21:29:09 GMT"
);
Expires = (
"Sat, 01 Jan 2000 00:00:00 GMT"
);
Pragma = (
"no-cache"
);

What could be the problem ? thanks for the help in advance

I have another issue with 2fa: after calling

challenge.code(/* the code */).authenticate()

response seems to be good enough

Optional

• some : <NSHTTPURLResponse: 0x600001fbef00> { URL: https://i.instagram.com/api/v1/accounts/two_factor_login/ } { Status Code: 200, Headers {
  ...

The problem is that the library produces the error

Authenticator.Error.invalidResponse(result.response)

when parsing this response. As far as I understand, it happens due to the following code in Authenticator+TwoFactor file:

guard value.isEmpty, let response = result.response as? HTTPURLResponse else { throw Authenticator.Error.invalidResponse(result.response) }

From my perspective this code should check for guard !value.isEmpty, since in current implementation the logic is to report an error when the value is here, which is obviously an incorrect behaviour.
