Unique username Help

Hi guys,

I need your help with this “Unique username” issue.
I know there are loads of topics about this subject but I still can’t figure out why it doesn’t work on my end.
I’m trying to simplify it as much as I can for now, to be able to make it work even tho I’d like to add some more features later on (such as “checks if the username is not already used and show a red message if it is” ).

Back to my issue. This is how I tried to do it.

By the way sorry for the French Inputs, here’s a quick translation :
Pseudo = Nickname (obviously)
S’inscrire = Sign up



This seems to read the database, but only the first Username inside of it.

For example, if a try to Sign up with Username = a, it won’t work because “a” is the first Nickname on the list. But then if I try with Username = ab, the user will be able to Sign up.

Hope you’ll understand my issue.
Thank you !

It’s probably a privacy rules issue.
