Issue in Laravel 5.3.6 when submitted request in Forgot Password

Issue in Laravel 5.3.6 when submitted request in Forgot Password.

Error Details

Call to undefined method Illuminate\Database\Query\Builder::notify()

Issue is in below file:

vendor\laravel\framework\src\Illuminate\Auth\Passwords\PasswordBroker.php

Line 69

It was working fine in Laravel 5.2 and seems not working in 5.3.6 version. Have you faced this issue?
