How can I attach media to mailable?

[anchan42]

I use model created events to notifications that create a mailable. The model has some media from the user's upload.
I tried $mediaItems = $this->bdReport->getMedia(); in the attachments method but the $mediaItems is empty.

It looks like the media are not saved yet when the created event is dispatched. What can I do?

This is my code:

In mailable

    public function attachments(): array
    {
        $mediaItems = $this->testReport->getMedia();
        $attachments = [];
        foreach ($mediaItems as $mediaItem) {
            $attachments[] = $mediaItem;
        }
        return $attachments;
    }

in model

    protected $dispatchesEvents = [
        'created' => TestReportCreated::class,
    ];

In listener

    public function handle(TestReportCreated $event): void
    {
         Notification::send($event->testReport->createdBy, new NewTestReportNotification($event->testReport));
    }

In notification

    public function toMail(object $notifiable): Mailable
    {
        $mailable = new TestReportRaisedMailable($this->testReport);
        $mailable->to($notifiable->email);
        return $mailable;
    }
