Generally speaking, if you see such a message, email us at support@bubble.is with a way to reproduce the bug (that message means there is a code bug we need to fix )
Might be something wrong with your idea (not sure yet to be honest) but what’s certain is that this message means we need to fix something, no matter how bad or good your idea is
The problem I had is that if it was an existing user than the app gave a message saying “this email is already registered”.
It logged in the user but I wanted to get rid of that message.
