Did Plaid Change Something About It's MFA? - plaid

Question

I had this little piece of code working perfectly returning account and transactions objects in response to the Plaid MFA questions. I'm not sure what went wrong as I (had not until it stopped working and I've since tried a few things) did not touch the code (to my recollection) and even checked several previous working versions to be safe. Anyhow I now get the following list of errors given the scenario:
1) If I try to US Bank MFA, it returns an MFA and after I answer it also returns a account and transactions object. At the end of that info in my terminal it also returns events.js 85 throw er; // Unhandled error event
2) If I try USAA or Bank of America I get the following error object for my response:
{ code: 1203,
message: 'invalid mfa',
resolve: 'The MFA response provided was not correct.',
access_token: 'test_bofa' }
It returns the MFA question though and when I answer with 'again', I get:
{ type: 'questions',
mfa: [ { question: 'You say tomato, I say...?' } ],
access_token: 'test_bofa' }
events.js:85 throw er; // Unhandled 'error' event
plaid.connect({username: req.body.cardName, password: req.body.cardPass, pin: req.body.pin}, req.body.type,
'test#plaid.com',
function (error, response, mfa) {
if (response == undefined) {
res.send(response);
} else if (response.hasOwnProperty('accounts')) {
res.send(response);
} else if (response.hasOwnProperty("mfa")) {
res.send(response);//If I remove this response it kicks me out right away. But with it, I receive an undefined MFA response.
plaid.step(response.access_token, req.body.answer, function (err, response) {
if (response == undefined) {
res.send(response);
} else if (response.hasOwnProperty("resolve")) {
res.send(response);
} else if (response.hasOwnProperty('accounts')) {
res.send(response);
} else if (response.hasOwnProperty('mfa')) {
res.send(response);
}
}
)
}
else {
response = "error";
response.send("something went wrong with Plaid");
}
}
)
}

Answer 1

As i understand during testing mfa code should be string or and array(if there are few questions). So if you enter mfa as an int you will get error.
'again' mfa will call one more mfa loop, and 'tomato' will finalize it.
