[SOLVED] Error: "Cannot read property 'isJoined' of undefined"

Hi,

I see the following error when connecting the Jibri to a JWT-enabled Jitsi. The call page fails to load and get timed out. However on checking chromedriver.log I see the following error:

 "Cannot read property 'isJoined' of undefined"

What could be the reason for this error? Where can I find the definition of the isJoined function? I see isJoined of “undefined”, so may be APP is not loading? Where can I find the necessary source for the same and debug it?

The Jibri source:
return APP.conference._room.isJoined();

override fun visit(url: String): Boolean {
    logger.debug("Visiting url $url")
    if (!super.visit(url)) {
        return false
    }
    val start = System.currentTimeMillis()
    return try {
        WebDriverWait(driver, 30).until {
            val result = driver.executeScript("""
                try {
                    return APP.conference._room.isJoined();
                } catch (e) {
                    return e.message;
                }
                """.trimMargin()
            )
            when (result) {
                is Boolean -> result
                else -> false
            }
        }

The error you see is that

is undefined. It means it fails to join the muc, as _room is the muc representation coming from lib-jitsi-meet. You either need more information before this error (not user there is more in the log file before you see this). I purposed to you a way to debug it from the browser on your PC. Jibri with JWT token enabled Jitsi
