I’m running openHAB 4.0.0.M1 with the ‘JavaScript Scripting (Nashorn)’ installed.
But getting the error, not sure if I need something else?
Just had a quick look, and I can’t find graalVM.
You shouldn’t need anything else. Did you try with the adjusted version I loaded 1h ago? I made a slight change that could have an impact.
I need to copy/paste from 2 installation since I can’t find the rule template in OH4. But if I did it correct, I’m getting now following error:
Script execution of rule with UID '07f5211181' failed: java.lang.NullPointerException: Cannot invoke "java.time.temporal.TemporalUnit.addTo(java.time.temporal.Temporal, long)" because "unit" is null
I just tried with an OH4 snapshot and Nashorn js installed. It runs fine.
Check out line 66 in the script. That’s where I have made the change. It should be:
timer = ScriptExecution.createTimerWithArgument(now.plus(delayInSeconds, ChronoUnit.SECONDS), func, function() {
That’s correct, I’ve got the latest version. But still having:
2023-04-26 19:38:46.775 [ERROR] [internal.handler.ScriptActionHandler] - Script execution of rule with UID '07f5211181' failed: java.lang.NullPointerException: Cannot invoke "java.time.temporal.TemporalUnit.addTo(java.time.temporal.Temporal, long)" because "unit" is null
Will have some other tests tomorrow.
Guess something is wrong in my system, but not sure where. Everything else seems to be working fine. Can I add extra debugs to the logs?
Just did an upgrade towards 4.0.0.M2, but no luck 
When I check the installed bundles, I see I have 2 JavaScript Scripting? Not sure why. But no difference with 1 installed, the other or both. Always the same error.

You installes both the old javascript addon (nashorn) and the new one (using graalvm). It is likely the code is run using the newer one. I did not test that, so that’s likely the problem. I will look into it when I move to OH4.
@brononius A version for OH 4.0 for the JavaScript Scripting Add-on (ECMAScript 2022+ ES6) is now available here.

Thanks!

@lvdh
“huisvuil diftar” and “gft-diftar” should already work (“huisvuil” and “gft” are in the search strings and it looks for substrings.
Do you have an example output where “snoeihout” and/or “grofvuil” are used? I can then add them.
