no script engine found with name 'JavaScript

What is the reason for reporting "no script engine found with name 'JavaScript'"?

@coderzpw1 please share more details about your environment.

How do you run the Zeebe worker?
Do you use the provided Docker image?

It works for me with the latest Docker image zeebe-script-worker:1.1.0.

This error is caused by the high JDK version. Now it's OK to change to jdk11

This error is caused by the high JDK version.

True. JavaScript is removed since JDK 15.

Instead, we could use the Docker image for now. In the future, we need a different way, for example, use GraalVMs JavaScript.

Ok, I got it. Thank you for your answer.
