Laravel 5.8 Password Reset undefined variable $errors

I'm having trouble resetting my password. The Forget password is working good and I'm getting the email however when I click on the Reset Link button I get redirected to the password reset page and throws an error: undefined variable $errors.

Password reset is managed by Laravel doesn't it? If so then why I'm getting this

Code:

ForgetPasswordController.php

<?php

namespace App\Http\Controllers\API;

use Illuminate\Foundation\Auth\SendsPasswordResetEmails;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Password;
use Illuminate\Support\Facades\Validator;
use Illuminate\Support\MessageBag;

class ForgetPasswordController extends BaseController
{
    use SendsPasswordResetEmails;

    public function __construct()
    {
        $this->middleware('guest');
    }

    public function sendResetLinkEmail(Request $request)
    {
        $validator = Validator::make($request->only('email'), [
            'email' => 'required|email',
        ]);

        if ($validator->fails()) {
            return $this->sendError($validator->errors()->first());
        }

        // We will send the password reset link to this user.
        $response = $this->broker()->sendResetLink(
            $this->credentials($request)
        );

        if (Password::RESET_LINK_SENT == $response) {
            return $this->sendResponse('A password reset message was sent to your email address');
        }

        return $this->sendResetLinkFailedResponse($request, $response);
    }

    protected function validateEmail(Request $request)
    {
        $validator = Validator::make($request->only('email'), [
            'email' => 'required|email',
        ]);

        if ($validator->fails()) {
            return $validator->errors();
        }

        return false;
    }

    protected function sendResetLinkFailedResponse($request, $response)
    {
        $errors = $this->parseErrors(['email' => trans($response)])->first();

        return $this->sendError($errors);
    }

    protected function parseErrors($provider)
    {
        if ($provider instanceof MessageProvider) {
            return $provider->getMessageBag();
        }

        return new MessageBag((array) $provider);
    }
}
