Reset password in laravel nova - php

Question

I'm trying to combine Laravel project and Nova admin panel. In the project I need to reset Nova password, But there is a FatalThrowableError error in PasswordBroker.php file.
This is the error
This is my PasswordBroker.php file.
<?php
namespace Illuminate\Auth\Passwords;
use Closure;
use Illuminate\Support\Arr;
use UnexpectedValueException;
use Illuminate\Contracts\Auth\UserProvider;
use Illuminate\Contracts\Auth\PasswordBroker as PasswordBrokerContract;

{
protected $tokens;
protected $users;
protected $passwordValidator;

UserProvider $users)
{
$this->users = $users;
$this->tokens = $tokens;
}
public function sendResetLink(array $credentials)
{
$user = $this->getUser($credentials);
if (is_null($user)) {
return static::INVALID_USER;
}
$user->sendPasswordResetNotification(
$this->tokens->create($user)
);
return static::RESET_LINK_SENT;
}
public function reset(array $credentials, Closure $callback)
{
$user = $this->validateReset($credentials);
if (! $user instanceof CanResetPasswordContract) {
return $user;
}
$password = $credentials['password'];
$callback($user, $password);
$this->tokens->delete($user);
return static::PASSWORD_RESET;
}

return static::INVALID_USER;
}
if (! $this->validateNewPassword($credentials)) {
return static::INVALID_PASSWORD;
}
if (! $this->tokens->exists($user, $credentials['token'])) {
return static::INVALID_TOKEN;
}
return $user;
}

}
public function validateNewPassword(array $credentials)
{

list($password, $confirm) = [
$credentials['password'],
$credentials['password_confirmation'],
];
return call_user_func(
$this->passwordValidator, $credentials
) && $password === $confirm;
}
return $this->validatePasswordWithDefaults($credentials);
}
protected function validatePasswordWithDefaults(array $credentials)
{
list($password, $confirm) = [
$credentials['password'],
$credentials['password_confirmation'],
];
return $password === $confirm && mb_strlen($password) >= 6;
}
public function getUser(array $credentials)
{
$credentials = Arr::except($credentials, ['token']);
$user = $this->users->retrieveByCredentials($credentials);
if ($user && ! $user instanceof CanResetPasswordContract) {
throw new UnexpectedValueException('User must implement CanResetPassword interface.');
}
return $user;
}
public function createToken(CanResetPasswordContract $user)
{
return $this->tokens->create($user);
}
public function deleteToken(CanResetPasswordContract $user)
{
$this->tokens->delete($user);
}
public function tokenExists(CanResetPasswordContract $user, $token)
{
return $this->tokens->exists($user, $token);
}
public function getRepository()
{
return $this->tokens;
}
}
Here I want to reset current password using email. Does anyone have a idea to fix this issue ?
