A bit more context... the error is coming from

TwirpRPC.js

calling Axios for a wss request inside folder

livekit-server-sdk > dist

TwirpRPC

is being called in

EgressClient.js

as assigned to

this.rpc

which processes the

startTrackEgress

function. And unless I've totally lost it, Axios isn't a websocket client.

@quiet-parrot-71005 where are you specifying your websocket URL? When you create your egress client? I haven’t personally used trackEgress over WebSocket before. Could you paste some code (with the wss URL redacted)?

Ah! can you try usinng https:// with the URL?

Thanks for the reply guys. I've got my websocket and egress client defined earlier in the function. Based on @dry-elephant-14928’s suggestion, I changed both urls to https and now don't see the Axios error, the

egress_started

event begins followed quickly by

egress_ended

with

error

field

error: 'URL was not provided',

Here is my function:

async function livekitWebhook(req) {
    const apiKey = process.env.LIVEKIT_API;
    const secret = process.env.LIVEKIT_SECRET;
    const webhook = "https://<our-websocket-url>.<http://appspot.com|appspot.com>";
    const liveKitUrl = 'https://<our-livekit-host-url>.livekit.cloud';

    const receiver = new WebhookReceiver(apiKey, secret);
    const egressClient = new EgressClient(liveKitUrl, apiKey, secret);

    try {
        const event = receiver.receive(req.body, req.get('Authorization'));
        console.log('Received LiveKit Webhook data');
        console.log(event);

        if (event.event == 'track_published') {
            console.log('++ Event is track published, starting webhook code ++');
            
            const roomName = event.room.name;
            const trackID = event.track.sid;

            console.log('Room Name :: ' + roomName + ' :: TrackID :: ' + trackID + ' :: webhook :: ' + webhook);
            const info = await egressClient.startTrackEgress(roomName, webhook, trackID);

            console.log('--------------------------------');
            console.log('Received Info details');
            console.log(info);
            console.log('--------------------------------');
        }

        return event;
    } catch(err) {
        console.log('Error with livekit webhook');
        console.log(err);
        return err;
    }
}

is this an audio or video track that you are attempting to Egress?

yes audio only, for STT purposes

ok, good. then the error indicates there's most likely an issue with your websocket receiver

is that just a matter of checking the event.track.mimetype value?

you'd want to check track.type. the MIME will not be

audio/x-raw

either, as the client has published opus

aha very useful. thank you
