I am quite new in laravel/lumen framework. I am using lumen 5.2 to build a restful API. For authentication, I am trying to implement JWT authentication I am following this https://laravelista.com/json-web-token-authentication-for-lumen article for guidance. I install and configure this https://github.com/tymondesigns/jwt-auth packages. It works fine and gives me following error if i do not provide a token {"error":"token_not_provided"} .But when i am trying to generate a token by passing email and password in a post request then it fails and give following error.

Here is my Authcontroller code:
namespace App\Http\Controllers;
use Illuminate\Http\Exception\HttpResponseException;
use JWTAuth;
use Tymon\JWTAuth\Exceptions\JWTException;
use Illuminate\Http\Request;
use Illuminate\Http\Response as IlluminateResponse;
class AuthController extends Controller{
/**
* Handle a login request to the application.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function postLogin(Request $request)
{
try
{
$this->validate($request, [
'email' => 'required|email|max:255', 'password' => 'required',
]);
}
catch (HttpResponseException $e)
{
return response()->json([
'error' => [
'message' => 'Invalid auth',
'status_code' => IlluminateResponse::HTTP_BAD_REQUEST
]],
IlluminateResponse::HTTP_BAD_REQUEST,
$headers = []
);
}
$credentials = $this->getCredentials($request);
try
{
// attempt to verify the credentials and create a token for the user
//$customClaims = ['email' => '[email protected]', 'password' => 'password'];
if ( ! $token = JWTAuth::attempt($credentials))
{
return response()->json(['error' => 'invalid_credentials'], 401);
}
}
catch (JWTException $e)
{
// something went wrong whilst attempting to encode the token
return response()->json(['error' => 'could_not_create_token'], 500);
}
// all good so return the token
return response()->json(compact('token'));
}
/**
* Get the needed authorization credentials from the request.
*
* @param \Illuminate\Http\Request $request
* @return array
*/
protected function getCredentials(Request $request)
{
return $request->only('email', 'password');
}
}

I google it a lot but not get any solution yet. Please help me to figure it out.
thank in advance.
Here is the directory structure of vendor folder
You may write your own auth configuration file in config/auth.php (if it doesn't exist, you may create on yourself). See configuration here.
![![][vender folder]](https://i.sstatic.net/ONxU8.jpg){kind=link}
<?php
return [
/*
|--------------------------------------------------------------------------
| Authentication Defaults
|--------------------------------------------------------------------------
|
| This option controls the default authentication "guard" and password
| reset options for your application. You may change these defaults
| as required, but they're a perfect start for most applications.
|
*/
'defaults' => [
'guard' => env('AUTH_GUARD', 'api'),
],
/*

|

| here which uses session storage and the Eloquent user provider.
|
| All authentication drivers have a user provider. This defines how the
| users are actually retrieved out of your database or other storage
| mechanisms used by this application to persist your user's data.
|
| Supported: "session"
|

'providers' => [

Fortunately, I create a simple JWT Authentication implemented in Lumen here.
