these two errors happened in livekit server sip, why it is happened and how to fix it and debug it WARN livekit.agents agent/worker.go:465 received availability response for unknown job WARN livekit.transport rtc/transport.go:830 error reading data channel

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

the deployment in vm using docker is quiet old, how to check it

I'd be happy to help you check the version of your LiveKit server that's running on a VM with Docker. Here’s a simple way to do it: 1. First, SSH into your server. 2. Then, run these commands:

cd /opt/livekit
sudo docker-compose logs

These commands will show you the logs, and you’ll usually find the version information of your LiveKit server there. If you need any more help, just let me know—I’m here for you! Sources: Deploy to a VM | LiveKit Docs

this is my livekit server version v1.8.4

Thank you for reaching out! Let me walk you through the errors you're seeing and some helpful steps to debug them: • "received availability response for unknown job": This usually happens when a worker gets an availability response for a job ID that’s no longer active. It might be due to timing things like the job being cancelled or already completed. The server notes this as a warning but keeps running smoothly. • "error reading data channel": This points to a problem reading from a WebRTC data channel, which can happen because of network hiccups, sudden client disconnects, or mismatches in the data channel’s state. Here are some steps you can try to debug these issues: 1. Take a look at the server and agent logs to find more context—check the job IDs and timestamps carefully. 2. Use the dashboard to review the room and participant status; this might reveal any unusual patterns. 3. Make sure all parts of your setup (server, agents, SDKs) are running compatible versions to avoid any protocol mismatches. 4. Look into client connectivity and double-check your data channel settings (like whether it’s reliable or unordered). If you’re still facing problems after these steps, it would be great to gather some diagnostic info like job IDs, timestamps, full log excerpts, and details about your deployment environment. This info will be really helpful for further troubleshooting or if you decide to reach out to the LiveKit community for support.

is there a newer version of livekit server that solved the issue? so i can update to it

Thank you for reaching out! I wanted to let you know that there are indeed newer versions of the LiveKit server available after v1.8.4, like v1.9.0 and v1.9.1. These updates come with various improvements and bug fixes. While the changelogs don’t specifically mention the exact errors you’ve encountered, upgrading could still be really beneficial. It’s generally a good idea to update to the latest version, as it might bring stability enhancements and other fixes that could help with your issues. Just a friendly tip—make sure to test the upgrade in a staging environment first before rolling it out to production, to keep everything running smoothly. If you need any help with that, I’m here for you!

also i have

Client":{"sdk":"PYTHON","version":"1.0.6","protocol":15}

(legacy worker)

Client":{"sdk":"PYTHON","version":"1.0.12","protocol":16}

(new worker) why this occur and how to fix it

I'd love to help you sort out the mismatched SDK versions and protocols. Could you please share a bit more about your setup? • Are both the legacy and new workers running at the same time in your deployment? • Have you recently made any updates to components like the server, SDKs, or workers? • Are you noticing any specific issues or error messages because of this mismatch? Understanding these details will really help us get to the bottom of the issue and find the best solution for you.

unning at the same time in your deployment? yes although my agents share the exact same codebase • Are you noticing any specific issues or error messages because of this mismatch? yes some call are not being answered

It looks like the issue is coming from mismatched SDK versions and protocols, which can sometimes cause connectivity hiccups. Don’t worry though—here’s a friendly step-by-step to help you get it sorted out: 1. Make Sure SDK and Protocol Versions Match: Try updating all your agents to use the same SDK version and protocol. For example, sticking with Python SDK 1.0.12 (protocol 16) across the board can really help avoid confusion from mixing it with SDK 1.0.6 (protocol 15). 2. Check Agent Compatibility: Double-check that all agents are correctly reporting their SDK, version, and protocol when connecting. If these don’t line up, calls won’t be able to connect properly. 3. Turn On Detailed Logging: Enabling debug-level logging will capture

ClientInfo

during connection attempts, which is super helpful for spotting any mismatches or compatibility issues. 4. Update Protocol Dependencies: Make sure all parts are using compatible versions of the LiveKit protocol module. This keeps everything in sync between client and server. By aligning your SDKs, keeping protocols consistent, and reviewing detailed logs, you’ll be well on your way to resolving this.

does this error common? Make Sure SDK and Protocol Versions Match: Try updating all your agents to use the same SDK version and protocol. For example, sticking with Python SDK 1.0.12 (protocol 16) across the board can really help avoid confusion from mixing it with SDK 1.0.6 (protocol 15

I completely understand how frustrating it can be when SDK and protocol versions don’t quite match up in LiveKit—this is a known issue that can sometimes cause compatibility hiccups. Making sure the versions line up is a really important step to keep everything running smoothly between the client and server. That’s why LiveKit puts a strong emphasis on checking version compatibility when you run into problems. That said, I want to be honest with you—there isn’t specific data on how often developers come across these mismatched version issues. It’s definitely something to watch out for, but the exact frequency isn’t documented in the resources we have. If you ever need help with this, don’t hesitate to reach out—we’re here to support you!
