Firebase [ ERROR ]

[swipe13]

[I have been getting two errors in firebase only

I started by getting the auth/invalid-email error.

through this email I went searching and they say that it is the formatting of the email itself that has to be in string and I checked and the email is in string but the error continues after that I defined an email in the code with string type and the next error that gives me is

auth/internal-error I tried everything and I don't know what it can be
