[SOLVED] Air pollution data from luftdaten.info

Unfortunately there was obviously a change in JSONPATH in OH 2.2 stable (?)

I get:
Error executing the transformation 'JSONPATH': Invalid path '$[0].sensordatavalues[1]

Anyone who solved this already?

EDIT:
After a reboot the issue was solved.
In general my first impression about 2.2. is that it’s more sensitive to updates (rules / items etc) while running.
