An error keeps happening when I try to generate videos; it keeps saying that the maximum character limit is 2000. However, I've recently generated videos, and it accepted 4000+ characters.

Hi HeyGen Support,
After your API update announced (Third-Party Integrations, Custom LLM/TTS), our LiveAvatar integration stopped working.
Issue:
• SDK version 0.0.11 (latest on npm) logs "New unsupported event type" warnings
• Session connects successfully (shows "Live" status) but no audio plays
• No mic permission prompt appears
• app.liveavatar.com works fine with the same avatar
Details:
• Avatar ID: 513fd1b7-7ef9-466d-9af2-344e51eeb833
• API Key starts with: 81814718-d914-...
• Integration was working perfectly until this afternoon
It appears the backend now sends event types that SDK 0.0.11 doesn't recognize. Please publish an updated SDK to npm ASAP since our service is down.
Thank you,
Joe Pilcher

I am using Heygen Free tier.

After the API update announced 20th March (Third-Party Integrations, Custom LLM/TTS), our LiveAvatar integration stopped working.
What we're seeing:

I saw that Avatar V is now available for Digital twins. How can I use it through the API?
I cannot find Avatar V in the API Docs.

The Avatars (Digital Twins) I use all have about 3 minutes of Footage that I uploaded.

Hi HeyGen Engineering Team,

Hello,HeyGen

Hi team, I’m integrating HeyGen into a project workflow and have run into a critical issue that I need clarification on.

I am using the API to which I send audio files to generate a speaking video (Avatar created using image), but the issue is that when I add some silence in the audio, or when I just send a silent audio, instead of the avatar remaining still, it keeps showing awkward movements as if it is speaking but with the mouth closed. I would like to avoid that and have it so that the avatar remain still with natural small movements during those silent moments instead of acting like a weird mime. Is there a way to do that ?
