Using HeyGen api in React+tsx

My team and I have been trying to use HeyGen api to render the avatar and communicate with it in real-time,
while the audio is working fine, the video is stuck in the first frame, since we would be using HeyGen avatar in integration with our company's agent, it's is something that we require solved.

Audio File in Avatar IV API Request

Currently we have to send a Heygen Voice ID in the body params in the API request for Avatar IV generations.
The HeyGen Web App allows users to upload custom audio files to use.
Is it possible to do this with the API?

Interactive Avatar 1 Hour Cutoff Issue

Hi,
I have been streaming a HeyGen Interactive Avatar and exactly at the 1 hour mark from streaming.start_time, the streaming is cut off. We've been in contact with HeyGen Support and they handed us a live-kit-avatar webpage with their API Key so that we could reproduce the same issue. Even after using their key, we faced the same issue and started getting 401 Unauthorized exactly 1 hour from the start time. Has anyone faced a similar issue or knows how to solve it?

Critical Issue: Avatar streams dropping

Critical Issue: Avatar streams are dropping immediately after speech is queued with event type 'stream_disconnected' and detail: 5. This happens consistently across browsers (Safari, Firefox) and provides no error codes or messages. The issue occurs regardless of our STT implementation, session keepalive, or event handling. This appears to be a fundamental HeyGen streaming service issue that's blocking my production deployment.
