Solved: sessionErrorKey persists after successful login attempt

[kwiat1990]

Hi, I have in root.ts loader more or less this logic to return user from the session:

 const user await authenticator.isAuthenticated(request);
  let session = await getSession(request.headers.get("cookie"));
  let error = session.get(authenticator.sessionErrorKey);
  if (error) {
    return json({ error });
  }
  ...

The problem with this solution is that after a failed login attempt the sessionErrorKey get write into the session. In case the next login attempt is successfully, the error won't get removed from the session. I have also tried to manually call sesson.unset(authenticator.sessionErrorKey) but it didn't remove the key. So my question is how it should be done correctly?

Btw. I also use Remix-Auth-Socials.

It always helps to implement things on one's own, so the core concepts can be better understood. It's true that a session flash message gets unset after it gets read in the loader BUT there's one condition, which was not obvious for me after reading Remix docs: after reading flash message, one has to commit session: return json({...}, { headers: await commitSession(session) } } from the loader.
