Hi. It looks like you are using an older version of Burp. We'd always recommend staying up to date with our latest releases. You can find our latest downloads and releases here: https://portswigger.net/burp/releases If you're using the installer/platform version of Burp, then you will need to upgrade to a more recent version to use this extension. If you are using the standalone JAR file to run Burp, you will need to use a minimum Java version of Java 21 to use this extension.
