ignore them rather then erroneously attempting to send a null to the
Companion.

Alter the way Companion Updates Happen – Use Push

The AI Client code (in the browser) now downloads the new
Companion (from the service) and “pushes” it to the Companion using a
mechanism similar to the mechanism used to send assets to the
Companion. This eliminates difficulties encountered when a proxy
exists between the Internet and the AI user’s location.
