map.html not found

[turbocyx]

Have Iobroker and openhabpanel installed on my raspberry 4.
Installed and configured this widget IMHO as it is written in the Help ...
BUT: no matter what path I configure (eg /static/habpanel-widget-googlemaps/map/) I always get the massage "File habpanel-widget-googlemaps/map/index.html not found: {}" (path variies)
The full path for the map file is: /etc/openhab/html/habpanel-widget-googlemaps/map/map.html
So what path should I type ion the config? Or ist this a permission problem?
-rwxr--r-- 1 openhab openhab 6666 29. Mai 13:52 map.html
Any help would be very much apreciated

BTW: Is it possible to feed Items vom Iobroker to Lat/Long eg. the actual coordinates of my car?
