laravel query bug

[medbak]

• Laravel Version: Laravel Framework Lumen (7.1.3) (Laravel Components ^7.0)
• PHP Version: PHP 7.3.19-1+ubuntu20.04.1+deb.sury.org+1 (cli)
• Database Driver & Version:

Description:

I tried to execute this query :
$email = Email::where('email', false)
->first();
normally the result must be null but I get the first line in the table,
even if tried
$email = Email::where('email', false)
->get();
it returns all the values.

Email::whereNull('email')->get().

Thanks,
But what the returns of
$email = Email::where('email', false)
->first();
must be empty because in the database there is no email named false.
Flase is the result of another test, so the result will be passed to the query

Email::where('email','=','false')->first()
