catalog_not_connected
HTTP status: 422 (Unprocessable)
Title: Catalog not connected
Cause
The WhatsApp number that sends the message has no catalog, or the catalogId is not the one connected to it. The message was not sent.
How to fix it
Save the id of the catalog connected in Meta on the number that sends, then send again. Use the same id in the message.
Call the endpoint named below first, then send the request again.
Endpoint: PATCH /v2/whatsapp/phone-numbers/{id}
Every error carries requestId and the Request-Id header. Send it when you write to support.
