Call to a member function createToken() on null? - laravel

Question

When I used the passport package , I encountered this error
Call to a member function createToken() on null
Why do I get this error?
This is my code :
$users = Users::where('Email' , $username)
->where( 'Password' , $password)
->where('UserStatus' , config('global.active'))
->first();
if($users) {
$success['token'] = $users->createToken('MyApp')->accessToken;
return response()->json(['success' => $success], $this->successStatus);
} else {
return response()->json(['error'=>'Unauthorised'], 401);
}

Answer 1

$user = Auth::user(); is unnecessary and is what is causing your error.
$user = Users::where('Email' , $username)->where( 'Password' , $password)->where('UserStatus' , config('global.active'))->first();
if($user){
$success['token'] = $user->createToken('MyApp')->accessToken;
return response()->json(['success' => $success], $this->successStatus);
}else{
return response()->json(['error'=>'Unauthorised'], 401);
}

If $users were null, there's no way that part of the control structure where createToken is getting called would be reached. I wonder if this is a red herring, and there's some middleware at work here. There are actually three instances of a method by that same name, and the namespace in your error message is notable absent there:
/vendor/laravel/framework/src/Illuminate/Auth/Passwords/PasswordBroker.php
/vendor/laravel/passport/src/ApiTokenCookieFactory.php
/vendor/laravel/passport/src/HasApiTokens.php
That last one is a trait being used by the User model, and is the one you're calling. But I'm wondering if that error is actually coming from one of the other two. Check your error-log, probably in /storage/logs/laravel.log, and see if there's a stack-trace that might lend a clue.

You can do other way around to make it work.
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
public function authenticate(Request $request)
{
// add UserStatus logic here if any
if(Auth::attempt(['Email' => $request->username, 'Password' => $request->password], $request->remember))
{
$user = Auth::user();
$success['token'] = $request->user()->createToken('MyApp')->accessToken;
return response()->json(['success' => $success], $this->successStatus);
}
return response()->json(['error'=>'Unauthorised'], 401);
}
