Issue connecting to https://playwright.microsoft.com/ web sockets

[sylvesteraswin]

Hello,

I am trying to use https://playwright.microsoft.com/ for a project. The intension is to connect to cloud browser instance using a web socket url. I am unable to use this feature due to the below error message

Error message

Sample code

pw, err := playwright.Run()
if err != nil {
    return "", err
}
defer pw.Stop()


// // Start a browser server
browser, err := pw.Chromium.Connect(browserInstanceUrl, browserInstanceOptions)
if err != nil {
    return "", err
}
defer browser.Close()

I don't have a service instance to test with. But in the sample code, the authentication header is not set before connecting. Could this be the reason?
