This error means that you've tried to send a WhatsApp template that is not approved or does not exist in your Twilio account, or the template in your Twilio account and in LiveAgent WhatsApp number message templates section are not identical.
Not receiving new messages
If your WhatsApp number is connected to your LiveAgent account and active but not fetching new WhatsApp messages, please double-check the WhatsApp sender in the Twilio console. If the sender is missing or has an incorrect Webhook URL for incoming messages & Status callback URL set up, you won't be able to receive new messages.
Do not forget to replace account.ladesk.com with your real LiveAgent account URL.
All messages sent to you while the Webhook URL for incoming messages & Status callback URL is missing or wrong are lost and won't be fetched additionally after fixing the URLs.
This error is displayed in a WhatsApp ticket when the recipient is not correct or the selected phone number does not have a WhatsApp account.
