To fix WhatsApp message delivery:

1. Either upload the missing image file:
   1d32b5fbab0f494cae443b4188a83ca3.jpg

2. Or update your event's invitation_image_url to use an existing file

3. Meta's server must be able to download the image at the URL you provide,
   otherwise the message will not be delivered even though you get HTTP 200.

4. Check webhook logs to see the actual delivery status.
