auth()->user cannot be read after login in middleware ?

I have created a middleware and placed in

app.php

app.php

file on laravel side. I try to read value in every request but the problem is that I can't read any property from

auth()

auth()

after login. Yes, on the first request the

auth()

auth()

does not exist, but after login it should be readable. Moreover, I have placed some data in the

Session::put('some_data', $data)

Session::put('some_data', $data)

, even these data do not exist(I checked with debug).

Thank you anyway!
