A generic error message shown on the email verification screen when a specific one is expected

I’m testing the out-of-the-box email verification flow with the new Universal Login.
After registering as a new user, I get an email with a link to confirm my address. When I click on it, it shows that the email was verified - happy path works fine.

But I’m trying to test some error scenarios and what I’ve found is that I always see the generic error message even in cases which I’d expect to see a specific, more useful, message:

  1. When I click on the same link for the second time. I’d expect to see the message from alreadyVerifiedDescription, but I see the text from unknownErrorDescription instead.
  2. When I click on a link which hasn’t been previously used but is expired, I’d expect to see the message from auth0-users-expired-ticket field but I, again, see the message from unknownErrorDescription.

Is it me doing something wrong, or is there a bug in Auth0 causing the generic error message to be shown in all cases?
It’s very confusing for the users and prevents them recovering from the situation they got themselves into…

Looking forward to hearing from you.
