Error with authentication

Hello everyone,

I started working with Xano some days ago. I watched the tutorial how to set up the Authentication in Xano, but it didn´t work for me. When I try to Run and Debug the auth/login to get the authToken like the video, it returns this error:

Whoops! An error occurred.

Exception: Invalid name: mvpw2605:13134

On Youtube Xano's channel, they have said to me this error happens when I don't have any users in my database. But I have a table called 'user' and these 3 test users registered in:[Xano - Users.png]
The same error happens in both situations:

Login:[Xano - Login error.png]
Sign up:[Xano - Sign up error.png]
Can anyone help me? I would be grateful for this!
