ReferenceError: "JSRule" is not defined in <eval> at line number 7

Hi, I have an OH3 installation on a Rpi4. I have installed the JavaScript Libraries. But with the provided script I do get an error. What did i wrong or what do I have to do to avoid below error?

I have followed precisely the instructions in[Ivan’s Helper Libraries - OH3, Python, JavaScrip to install the JS helper libraries. I have used these files to install the libraries: https://github.com/CrazyIvan359/openhab-helper-libraries/archive/5a452ef2367176654fa408c18917947c1502697b.zip )

After the installation I do get to following error:
2021-05-07 18:25:56.489 [ERROR] [ipt.internal.ScriptEngineManagerImpl] - Error during evaluation of script ‘file:/etc/openhab/automation/jsr223/javascript/personal/HelloWorld.js’: ReferenceError: “JSRule” is not defined in at line number 7

according to OH3 How to load Javascript rules.js? - #10 by CrazyIvan359

thanks for helping me out! Appriciated!
