hello! i use form action and post method to send creds to http://localhost:4433/self-service/login?flow=blalba (can't use on submit and updateLoginFlow for some reason) but i can't handle an error, for example if creds are invalid. it just redirect to http://localhost:3000/login?flow=blabla if valid - it's ok and redirect to after login default page i set error page url and expect that after bad creds (it might be 400 error (?)) it goes to error page when i can handle this error, but it doesn't Is this kratos logic or my mistake?
