Connexion lib jitsy meet

Hello I don’t know how to connect a jitsi client I’m developing with lib jitsy meet,

private options = {
“hosts”: {
“domain”: “”,
“muc”: “
“serviceUrl”: “//”,
“clientNode”: “”,
“testing”: {
“enableNoAudioDetection”: true,
"openBridgeChannel: websocket,
“p2p”: { “enabled”: true,
“stunServers”: [{“urls”: “”}]},
"makeJsonParserHappy: “even if last key had a trailing comma”,
“applicationName”: “Jitsi Meet”,
“confID”: “

And I don’t know if it’s functional … the event doesn’t react …

And when I run initJitsiConference(‘roomname’, options) it returns me
ERROR TypeError: Cannot read property ‘substr’ of null

It’s been a few days that I’ve been going around this problem without finding anything …

Thank you for your answer
