ScriptEngine for language 'application/javascript;version=ECMAScript-2021' could not be found for identifier


I am running openhab 3.4.1 and I want to use ECMAScript-2021.

I already installed the Javascript Transformation add-on, also the openhab-js and openhab rules tools via openhabian-config tool.

What have I to do, to use ECMA-Script-2021 in my openhab system?



This is wrong. You need to install the JS Scripting Automation add-on.
