[depixedprojects]

I am getting this error for notification. I followed all the step. and worked for some of my notification.

 return FcmMessage::create()
        // ->setData([
        //     'status' => $status,
        //     'link' => $link,
        //     'id' => $id,
        // ])
            ->setNotification(\NotificationChannels\Fcm\Resources\Notification::create()
                    ->setTitle($subject)
                    ->setBody($body)
                    ->setImage($icon));

Looks like I have been, maybe the error in mothed routeNotificationForFcm() on User model: public function routeNotificationForFcm() { return $this->deviceFCMs()->pluck('token')->toArray(); //or return 'string token'; }

The reason for this error is Passing of integer value.

The text in the error (TYPE_STRING), 121 describes that error is due to value integer 121 (while it is expecting a string) in your data somewhere. When you convert the value in string, it won't occur.

This is most likely due to data in FCM accepts string only.
