Stuck on Mint authentication

[BagMan9]

Running in docker, quickstart goes smoothly, but when it's time to actually run it, it does nothing and spits out an error of

mintapi:Not on Account Selection Screen
mintapi:Not on MFA screen

(MFA error paraphrased) and errors out. I'm not quite sure what I'm doing wrong. The YNAB connection is fine, again the quickstart went smoothly.

For mint, I'm entering my email (which I have triple-checked is my account ID), and copy-pasting my password. Lastly, for the MFA token, I am pasting it in as all 32 characters with no spaces (I initially was doing direct copy-paste from the website but that was pasting it as

XXXX
XXXX
...

so I thought that was the culprit, but it was not. Am I entering the MFA key wrong or is there something else?

Here is the full output log, just tried it again with spaces between each group of 4 characters and same issue:

You seem to be doing everything correctly (if only code would accept seemingly correct :) ). Have you tried running it outside docker and without the --headless option? You may gain some insight by seeing how it breaks in the browser when it's trying to sign in.
