I'm not sure, but it seems that json-prune doesn't work correctly at the moment.
For example:
adguard.com#%#//scriptlet("json-prune", "ThisIsTest.test123")
causes errors.

Not working at https://www.tv2.no/v/1549936/
tv2.no#%#//scriptlet("json-prune", "enabled", "testhide") (uBO syntax: tv2.no##+js(json-prune, enabled, testhide))
but this rule works tv2.no#%#//scriptlet("json-prune", "enabled")
