if I use Free tier of Livekit to create my agent. is there any time limit like 5 minutes, that I can talk to the agent on every session? why does the session closes on 5 minutes?

Thanks for reaching out, Nazmul. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

does deepgram has such limit? my agent is always closing in 5 minutes which has deepgram stt

Hey there! I totally understand your concern about the session time limit. Let me help clarify things for you. Deepgram actually doesn't have a strict 5-minute cutoff for speech-to-text like Google does. If your agent is closing after 5 minutes while using Deepgram, we'll want to dig a bit deeper to figure out what might be causing that. I'm here to help you troubleshoot and get to the bottom of this. Would you like to walk me through the details so we can solve this together?

so then why does deepgram crashes in every 5 minutes even though I was talking and online. this is my last error log:
