Code Snippet

I just realized this occurs when the to property was set to an object. Seems like Twilio should still handle this error better and give a more descriptive error message.

The error is now better surfaced after the migration to axios as the underlying request client in version 3.41.0: https://github.com/twilio/twilio-node/pull/542.

Closing as resolved.
