How do i fix thi

[Baconisyesssepic]

How could i fix this error "🚫 The eval engine provided in the config (Nashorn) doesn't exist. This could be due to an invalid engine name, or the engine not existing in your version of java (21.0.3)."

JMusicBot is built with Java 11, and the Nashorn engine is available in Java versions up to 14. You can either install a different version of Java (between 11 and 14), or set the evalengine field in your config file to something that is supported on Java 21 (no other engines have been thoroughly tested, but the Rhino engine might work). An example config with the engine set to Nashorn is available here.
