Error 131047 means you tried to send a free-form (session) message after the 24-hour customer service window closed.
Official Meta details: More than 24 hours have passed since the recipient last replied to the sender number. Solution: send the recipient a template message instead.

What the 24-hour window is

When a WhatsApp user messages your business number, Meta opens a customer service window. Inside that window you can send free-form replies (text, media, interactive messages) without a template. After 24 hours with no further inbound message from that user, the window closes and free-form sends fail with 131047.

How to fix it

1

Send an approved template

Use a Meta-approved template (Utility, Authentication, or Marketing as appropriate) from Flowella or a HubSpot workflow. Templates are allowed outside the window.
2

Or wait for the contact to message you

Any inbound message from the contact opens a new 24-hour window. A click-to-chat link makes that easy.
3

Do not retry the same free-form message

Retrying free-form content will keep returning 131047 until a window is open again.
