63031: Channels message cannot have same 'From' and 'To'

Twilio returns this error when your channel message request uses the same address for From and To. Use a sender address for From and a recipient address for To. For channel messaging, Twilio expects channel-specific addresses such as whatsapp:{phone_number}, messenger:{messenger_page_id}, messenger:{messenger_user_id}, or rcs:{unique_id}.

• Your API request sent the same channel address in both From and To.
• Your application copied a recipient address into From instead of using your Twilio-hosted channel sender.
• For WhatsApp, your request used the same whatsapp: address for both parameters instead of using your approved WhatsApp sender in From and the recipient in To.
• You passed a specific From value while sending with a Messaging Service, and that sender value matched the destination address.

• Update your request so From and To contain different values.
• Set From to a sender that belongs to your Twilio account and is hosted within Twilio.
• Set To to the destination user's channel address in the correct channel format.
• For WhatsApp, use your approved sender address in From and the recipient's WhatsApp address in To.
• If you send with a Messaging Service, provide MessagingServiceSid and omit From so Twilio can select a sender from your Sender Pool.
• Verify that each channel address uses the correct prefix and format before you send the request.
