title: Laravel kreait package unable to create the messaging service without a project ID
body: <p>I would like to use Firebase cloud messaging, so I installed <a href="https://github.com/kreait/laravel-firebase" rel="nofollow noreferrer">kreait laravel firebase package</a>
  I created a service account in firebase console, included the downloaded .json file in my root folder in laravel and used</p>
  <pre><code>FIREBASE_CREDENTIALS=app-XXXXX-firebase-adminsdk-XXXX-XXXXXXX.json
  </code></pre>
  <p>in .env</p>
  <hr />
  <p>Also created a controller for sending a push notification to a device</p>
  <pre><code>&lt;?php
  
  namespace App\Http\Controllers;
  
  use Illuminate\Support\Facades\Auth;
  use Kreait\Firebase\Messaging\CloudMessage;
  use Kreait\Firebase\Messaging\Notification;
  
  class PushNotifactionController extends Controller
  {
      public function sendPush(){
          $messaging = app('firebase.messaging');
          $deviceTokens = Auth::user()-&gt;deviceTokens()-&gt;pluck('device_token')-&gt;toArray();
  
          $message = CloudMessage::new();
          $message-&gt;withNotification(Notification::create('Title', 'Body'));
  
          $sendReport = $messaging-&gt;sendMulticast($message, $deviceTokens);
          
          return response()-&gt;json([
              'Successful' =&gt; $sendReport-&gt;successes()-&gt;count(),
              'Failed' =&gt; $sendReport-&gt;failures()-&gt;count()
          ]);
      }
  }
  
  </code></pre>
  <p>If I launch my Flutter app, firebase package creates a device token which i store in my database.
  But if I would like to trigger the <code>sendPush()</code> with postman i got this error:</p>
  <pre><code>&quot;message&quot;: &quot;Unable to create the messaging service without a project ID&quot;,
  &quot;exception&quot;: &quot;Kreait\\Firebase\\Exception\\RuntimeException&quot;,
  </code></pre>
  <p>From the firebase console I was able to send a notification to my phone.</p>
  <p>The package should autodiscover the service account and project ID.
  Help very appreciated!</p>
