Hi Shivangi.
This is a client-side log, which doesn't include information about the server-side stack trace of the error. Could you locate the server-side error? You can filter the error logs by Module = Extension to make it easier to find it.
The latest version fixes an issue which might be the same as you're experiencing. You can find details about the error that was fixed here: https://github.com/hardkoded/puppeteer-sharp/issues/1447
