Rules with JS not working

[maisen20 (Maisen)]

Hello

All my rules in the javascript language are not working.
Has anyone had the same problem? At least the two error messages below show that the “rule”-UID is undefined. So the variable ctx does not return this value!?

Example code:

var logger = Java.type('org.slf4j.LoggerFactory').getLogger('org.openhab.rule.' + ctx.ruleUID);

x = new Date();
h = x.getHours();
logger.info("Current hour: "+h);

var currentStatus = itemRegistry.getItem("test").getState();

Everything is working, except access of itemRegistry (the last line in my code).

Error logs:

Which ECMAScript engine? There is the default ECMAScript 5.1 which comes with openHAB and there is the GraalVM JavaScript add-on you can install separately. The two are not the same and rules written in one are not compatible with the other. When you do install the GraalVM add-on, for some reason it breaks the built in JavaScript right now (I’ve opened an issue but it’s not gained traction yet) so if you do install the add-on, you must only use that for your rules. It’s clear from the error tha…

Hi rossko57

Thank you for your very quick reply! Indeed, I installed JSScripting when I updated to oh3, simply because I thought that just then I can scripting with JS. Have now deleted this addon and restarted the server, now it seems to work.

Thanks a lot =)
