I’m not sure over the years if this script was part of openhab 3.x versions, but the error is new after updating to openhab Version 4.0.1:

Here the script (which I could not remember to put it there, so believe part of distribution)

This trigger can respond to file system changes. For example, you could watch a
directory for new files and then process them.

Not sure, but recognized that changed textual things configuration files not recognized in 4.0.1. Maybe the reasin is this script is not working?
I see no reason why it wouldn’t be. But it too is not a part of the official openHAB repos. I don’t know what, if any, succession plans they have should the lead developer disappear for whatever reason. But it runs on standard Python so at least you don’t have to worry about that going away or breaking.
