63053: When you send a message from a template, the template syncing process can take up to 10 minutes to complete. Wait a few minutes, and then try sending your message again

This error appears when you try to send a template message before the template sync has finished. Wait for the sync to complete, then send the message again. Twilio's Content Template Builder and Content API mirror templates across products, so newly created or updated templates may not be ready to use immediately.

• You sent the message before the template finished syncing in Twilio.
• You recently created or updated the template, and the mirrored template data has not finished propagating yet.

• Wait a few minutes, then retry the message send. Twilio indicates the sync can take up to 10 minutes.
• Send the message again only after the template is available in your template workflow and ready to use.
