Help using Mail

I modified my Mail sender, now I'm storing each file to the local disk and then getting it and attaching it. But I am not receiving the emails but no error in the console, any ideas?

Here is the code:

public function update(Request $request)
	{
		$booking = Booking::where('randomKey', '=', $request->reference)->first();

		if ($request->authcode && $request->cardbrand && $request->card4) {
			$booking->paid = true;
			$booking->korta_authcode = $request->authcode;
			$booking->cardbrand = $request->cardbrand;
			$booking->card4 = $request->card4;

			$booking->save();
		}
		
		$pdf_file = PDF::loadHtml('<h1>Hello world!</h1>');
	
		$fileName = "Bókun {$booking['id']}.pdf";

		Storage::disk('local')->put($fileName, $pdf_file->download($fileName));

		$file = Storage::get($fileName);

		if (app()->environment('production')) {
			Mail::to($booking->email)
				->cc("[email protected]")
				->bcc("[email protected]")
				->attach($pdf_file->stream())
				->send(new BookingConfirmation($booking));
		} else {
			Mail::send(new BookingConfirmation($booking), $booking, function ($message) use ($booking, $file) {
				$message->from('[email protected]', 'Bílahótel');
				$message->to($booking['email'])->cc('[email protected]');
				$message->subject("Bókun {$booking['id']} staðfest | Bílahótel");
				$message->attach($file);
			});
		}

		return $file;
	}

I needed to add one line to the mail controller like this :

->attachFromStorage("Bókun {$this->booking->id}.pdf");

Then my controller sending the email ended something like this:

$pdf_file = PDF::loadView('pdf.booking_confirmed', compact('booking'));
	
		$fileName = "Bókun {$booking['id']}.pdf";

		Storage::disk('local')->put($fileName, $pdf_file->download($fileName));

		$file = Storage::get($fileName);

		if (app()->environment('production')) {
			Mail::to($booking->email)
				->cc("[email protected]")
				->bcc("[email protected]")
				->send(new BookingConfirmation($booking));
		} else {
			Mail::to($booking->email)->send(new BookingConfirmation($booking));
		}
