sk-reflect parsing as object for no reason

[MinecraftNight4]

Describe the bug
SkJson and Skript Reflect have problems detecting jsons inside an expression.

To reproduce

effect json-rem %string% on %json%:
	trigger:
		remove key (expr-1) of json object from expr-2

When I trying to create this effect, shows this error:
"Expression 2 cannot have anything removed from it".

Expected behavior
You are supposed to be able to delete elements inside the json, but it doesn't make much sense for this to happen.
