iam getting this error twirp error unknown: request has missing or invalid field: ws_url when trying to upload the recording to s3 storage const fileOutput = new EncodedFileOutput({ filepath: fileName, output: { case: 's3', value: new S3Upload({ accessKey: AWS_ACCESS_KEY_ID!, secret: AWS_SECRET_ACCESS_KEY!, region: S3_REGION, bucket: S3_BUCKET_NAME, }), }, }); console.log('File output configuration:', JSON.stringify({ filepath: fileName, outputType: 's3', region: S3_REGION, bucket: S3_BUCKET_NAME }, null, 2)); // Use the exact method signature from your original working code console.log('Starting room composite egress...'); await egressClient.startRoomCompositeEgress( roomName, { file: fileOutput, }, { layout: 'speaker', }, );

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

the

ws_url

is not in your egress configuration and i dodnot have LIVEKIT_WS_URL in my nev

Thank you for reaching out! The

ws_url

is really important for the egress service to connect smoothly to the LiveKit server. I noticed it’s missing from your egress configuration, and since

LIVEKIT_WS_URL

isn’t set as an environment variable either, we’ll need to add it together. Here’s a simple way to move forward: • Add the

LIVEKIT_WS_URL

environment variable to your setup. For example:

LIVEKIT_WS_URL=<ws://your-livekit-server:7880>

. Just swap out

your-livekit-server

with your actual server address. • If you’re running the egress service locally, please make sure the

ws_url

points to the correct host IP address as Docker sees it (something like `ws://192.168.65.2:7880`). • For secure setups, it’s best to use

wss://

instead of

ws://

, unless you’ve specifically set

insecure: true

in your configuration. Once you’ve made these updates, just restart the egress service and give it another try. If you run into any other questions or need a hand, I’m here to help!

how to add

ws_url

to my egress configuration

To help you add the

ws_url

to your egress configuration, you’ll want to include it in the YAML configuration file under the top-level

ws_url

field. This tells the egress service which WebSocket URL of the LiveKit server to connect to. Here’s a simple example for you:

ws_url: <wss://your-livekit-url.com>

Just replace

<http://your-livekit-url.com|your-livekit-url.com>

with the actual URL of your LiveKit server. Remember to use

wss://

for secure connections, or

ws://

if you’re using insecure connections (when

insecure: true

is set). If you prefer, you can also set the

LIVEKIT_WS_URL

environment variable instead of changing the configuration file. Once you’ve made these updates, please restart the egress service and give it another try. If you run into any issues or have questions, I’m here to help—just let me know! Sources: pkg/config/pipeline.go | Self-hosting the Egress Service | LiveKit Docs | egress-sample.yaml

how to add

ws_url

to my egress configuration // Use the same URL conversion as the original working code const hostURL = new URL(LIVEKIT_URL!); hostURL.protocol = 'https:'; console.log(

Egress URL: ${hostURL.origin}

); const egressClient = new EgressClient(hostURL.origin, LIVEKIT_API_KEY, LIVEKIT_API_SECRET); const existingEgresses = await egressClient.listEgress({ roomName }); if (existingEgresses.length > 0 && existingEgresses.some((e) => e.status < 2)) { return new NextResponse('Meeting is already being recorded', { status: 409 }); } // Generate simple filename for S3 upload const fileName = `livekit/record/${roomName}.mp4`; console.log(

Generated filename: ${fileName}

); const fileOutput = new EncodedFileOutput({ filepath: fileName, output: { case: 's3', value: new S3Upload({ _// accessKey: AWS_ACCESS_KEY_ID!,_ _// secret: AWS_SECRET_ACCESS_KEY!,_ region: S3_REGION, bucket: S3_BUCKET_NAME, }), }, }); console.log('File output configuration:', JSON.stringify({ filepath: fileName, outputType: 's3', region: S3_REGION, bucket: S3_BUCKET_NAME }, null, 2)); // Use the exact method signature from your original working code console.log('Starting room composite egress...'); await egressClient.startRoomCompositeEgress( roomName, { file: fileOutput, }, { layout: 'speaker', }, ); console.log('Recording started successfully');

Thanks for reaching out! I wanted to share that the

ws_url

can’t be set directly through the JavaScript SDK for LiveKit Egress. Instead, it needs to be configured within the Egress service itself. Don’t worry—I’ll guide you through how to do this: Option 1: YAML Configuration File You can add the

ws_url

to the Egress service’s YAML configuration file like this:

api_key: your-api-key
api_secret: your-api-secret
ws_url: <wss://your-livekit-server.com>
redis:
  address: your-redis-address:6379

Then, just pass this file to the Egress service using the

EGRESS_CONFIG_FILE

environment variable. Option 2: Environment Variable Alternatively, you can set the

LIVEKIT_WS_URL

environment variable before starting the Egress service:

LIVEKIT_WS_URL=<wss://your-livekit-server.com>

These steps will help ensure your Egress service connects to the right LiveKit server. If you have any questions or need a hand with the setup, please feel free to ask—I’m here to help!
