Error "No script engine found for JavaScript"

java version "21.0.1" 2023-10-17 LTS

Java(TM) SE Runtime Environment (build 21.0.1+12-LTS-29)

Kindly advise

Thank you

After inspecting the code in the job it is quite clear why. The component uses JavaScript to evaluate the path. I have no idea why because it is actually not neccessary to use JavaScript because the component also use a JsonPath lib fully capable working with JSONPath.

Since Java 15 the JavaScript engine was removed from the default delivery of Java. I am sure if you run the job with Java 11 it will run because Java 11 has a JavaScript engine in place.

Thank you @Jan Lolling but if downgrade to Java 11, will it support Talend 8.0.1?

Yes of course. For sure better than the version 21!
