TCHMessageBuilder.addMedia() fails authentication

[twoeven]

Also submitted as support ticket #13959800 with more details.

This can be demonstrated using the twilio-conversations-demo-ios-swift project. All participants are chat. Sending basic messages, push notifications, editing metadata, all works correctly. However, when attaching media via TCHMessageBuilder.addMedia() the upload fails with Domain=signal.sdk.domain.error Code=4010 "No authentication provided".

This appears to be related to my production twilio account which has HIPAA features, as the same error does not happen in my development account. Uploading the media via the REST api works (example below), but I would prefer to stay in the framework.

Same behavior observed in TwilioConversationsClient 2.x and 3.1.0 (preferred) and 4.0.2

Excerpt from the trace log demonstrating the error:
