Unable to set/use token due to confusing errors

[Methodician]

Every time I try to run figcd auth (even if I pass a cookie arg) I get the following in sequence:

First:

Email and password authentication seems to work

Second:

Cookie argument missing, automatically retrieving fresh session cookies to start authentication
FIGMA_COOKIE='lots of stuff'; FIGMA_TSID=s0m3c0d3

Third:

Trying 2FA seems to work but I get the following two error blocks before it exits"

{"error":true,"status":400,"message":"Please enter your authenticator code","i18n":{"id":"auth.error.enter-two-factor-code","fallback_text":"Please enter your authenticator code","params":{}},"reason":{"missing":"two_factor","sms":true,"phone_number":"4648"}}

throw new Error("Authn cookie not found");
^

Error: Authn cookie not found

It's hard to know what to make of this because at first it looks like it's saying there was a problem with two-factor authentication (odd, because it's working elsewhere) but then it's talking about the Authn cookie (odd, because it claims it's resolving that, even if I provide one). I tried a lot of different approaches, but this is always what I get.

Lastly / Alternatively

if I simply generate an authentication token through the Figma UI and provide it as the argument, it looks like the program has concluded my token is expires? It's definitely not.

Command: figcd prepare -t figd_my-token-asdf1235asdf1235 -m dist/manifest.json
Output:

/Users/myname/.nvm/versions/node/v20.11.0/lib/node_modules/figcd/src/figma-helper.js:145
throw new Error('The provided token seem to be no longer valid.');
^

Node.js v20.11.0

Is this project still viable? Do I need to do something differently?
