When a WhatsApp message arrives, the webhook creates/updates the contact
and conversation fine (so the conversation appears in the Inbox), but
every message INSERT fails silently because the field names don't match
the messages table schema:
Webhook wrote Schema has
----------------- ----------
user_id (doesn't exist)
whatsapp_message_id message_id
direction: 'inbound' sender_type ('customer' | 'agent' | 'bot')
message_type content_type
media_type (doesn't exist)
status: 'received' status ('sending'|'sent'|'delivered'|'read'|'failed')
timestamp created_at
The insert error was caught and logged with console.error but silently
swallowed — the conversation update succeeded (its fields were right),
so the Inbox showed the contact and last message text, but opening the
thread showed zero messages. The 24-hour session timer also read
"no customer messages ever" and immediately marked the session expired.
Fixes in src/app/api/whatsapp/webhook/route.ts:
- processMessage() — message insert now uses the correct schema columns:
sender_type: 'customer'
content_type: message.type
message_id: message.id
status: 'delivered'
created_at: <ISO from Meta timestamp>
- handleStatusUpdate() — lookup uses message_id (not whatsapp_message_id)
and no longer sets updated_at (column doesn't exist on messages).
