Getting error - Unsupported message type, when using sendMulticast

[MuronOu]

Hello!

When I try to sen multiple message with sendMulticast from Kreait\Firebase\Messaging I recive an exception - _Unsupported message type. Use an array or a class implementing %sKreait\Firebase\Messaging\Message, despite the fact that I use CloudMessage or Notification.

use Kreait\Firebase\Messaging;
use Kreait\Firebase\Messaging\CloudMessage;
use Kreait\Firebase\Messaging\Message;
use Kreait\Firebase\Messaging\Notification;        

.....

        $message = [
            'title' => __('mobile_notifications_messages.posts.' . $eventName, [
                $author,
                $post->title,
            ]),
            'body' => 'Something'
        ];
        $message = Notification::fromArray($message);
        $response = $this->messaging->sendMulticast($message, $deviceTokens);

I use Laravel 5.8

Could you please help me with this?

You've almost got it!

The first $message array is actually the notification data, not a full message. You have two possibilities here:

Write the whole message as an array and use CloudMessage

$messageData = [
    'notification' => [ // <- This is the difference to your code
        'title' => __('mobile_notifications_messages.posts.' . $eventName, [
            $author,
            $post->title,
        ]),
        'body' => 'Something'
    ]
];
$message = CloudMessage::fromArray($messageData);

Write only the notification as an array and append it to a new CloudMessage

// Note that this variable is named $notification and passed
// to a new $message below
$notification = [
    'title' => __('mobile_notifications_messages.posts.' . $eventName, [
        $author,
        $post->title,
    ]),
    'body' => 'Something'
];

$message = CloudMessage::new()->withNotification($notification);

I hope this helps!
