No Settings in UI after migration to 4.2.0 from 3.4.0

Thanks for your quick reply. I’ve about 10 other js transforms that do not give any complaints. Just this one after the upgrade.

Those won’t complain until they are invoked. But the error means you do not have the JS Scripting add-on installed. “Transformation service JS … not found.” The “for pattern” part is just to help you find where that transform is being used. OH 4 does not come with JS any more. It must be installed separately. And the names have changed so that JS and javascript now refer to JS Scripting instead of Nashorn JS.

Not sure how I can remove the cache

Clear the Cache

Often when one encounters a problem with OH, particularly after an update, OH will refuse to run or certain parts of OH stop working. Some reported errors include: 500 or 404 errors when accessing the UIs lots of exceptions from Jetty or other core components in openhab.log OH refuses to start at all The first step in debugging the problem is to clear the tmp and cache. Installed OH If you are running an installed OH (openHABian, installed using apt or yum): openhab-cli stop openhab-cl…

This causes all the add-ons to be reinstalled.

Upgrades with the docker image also clear the cache as part of the upgrade and it can take some time for all the add-ons to be reinstalled.

Nothing suspicious in the logs.

I’m not asking for “suspicious”, I’m asking for relevant. Do you see the add-ons being installed on the first run after the upgrade? If you had JS transformations that means you had the JS Transformation add-on installed. That add-on no longer exists. So you should be at least seeing complaints about not being able to install the JS Transformation add-on in the logs. That’s relevant.
