Media is not available in model created event

[anchan42]

I create a new model from user input formwith pictures upload. I want to sent email notification out with picture attachements using model's created event. However the getMedia return null in the mailable. Here are my codes.

Model creation:

    public function store(StoreBdReport $request)
    {
        $data = $request->safe()->only(['plant_id', 'cost_center_id', 'bd_priority_id', 'bd_equipment_id', 'bd_type_id', 'reported_bd_description']);
        $data = array_merge($data, ['created_by_id' => $request->user()->id, 'bd_status_id' => 1]);

        $bdReport = new BdReport($data);

        //Add pictures to model media
        if ($pictures = $request->file('pictures')) {
            foreach ($pictures as $picture) {
                $bdReport->addMedia($picture)->toMediaCollection();
            }
        }

        $bdReport->save();

        //Retrieve query string stored in create method.
        $qryStr = $request->session()->pull('qryStr', '');

        return redirect()->route('bdr.bd_reports.index', $qryStr);
    }

Attachments in the mailable: getMedia return nothing here.

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

I got a workaround by calling BdReportCreated::dispatch($bdReport); after save() statement and remove the created event listener from the model. It works but not ideal.

How can I make media avialable in the event?
