Laravel what does mean "Undefined array key client_secret"

Question

So, I am trying to use the Google Login API for my web application. But the problem is, it doesn't work. I successfully installed the package Socialite and Auth. My Google OAuth2.0 is setuped. But when I click on the button Login with google, it gives me an error that I understand, but don't know how to fix. I'm searching this error for now 2 days on internet and I didn't find anything, that's why I'm posting now. Can someone help me ? Or put me on the right track :) I am using Laravel 8.0

Here is the problem that I get

Here is the function (both gives the same error)

public function redirectToProvider($provider)
{
    return Socialite::driver($provider)->redirect();
    //return($provider);
}

public function handleProviderCallback($provider)
{
    $user = Socialite::driver($provider)->stateless()->user();
    $authUser = $this->findOrCreateUser($user, $provider);
    Auth::login($authUser, true);
    return $user->token;
}

services.php

    'google' => [
    'client_id'     => env('GOOGLE_CLIENT_ID'),
    'client_secret' => env('GOOGLE_CLIENT_SECRET'),
    'redirect'      => env('GOOGLE_REDIRECT')
],

.env

GOOGLE_CLIENT_ID=XXXXXXXXXXXXXX.apps.googleusercontent.com
GOOGLE_CLIENT_SECRET=XXXXXXXXXXXXXXX
GOOGLE_REDIRECT=https://www.trivos.ca/home
