<?php

Solution:

Go to mhn-core-ms\app\Services\CustomPasswordBroker.php

And change this line all

The base class Illuminate\Auth\Passwords\PasswordBroker contains the sendResetLink function with the following signature:

public function sendResetLink(array $credentials, $callback = null)

And change all the place request to callback

All code here

After that run this command

php artisan config:clear
php artisan route:clear
php artisan view:clear
composer dump-autoload
