ClassCastException for Strings within grouping fucntions

[pza94]

Hi there,

I created a matcher that extracts a string from a given request object, and checks if that is in a given group:

g4(keyGet2(r.obj, "/customer/:cid/*", "cid"), p.dom )

When I try to call enforce it throws a ClassCastException.

java.lang.ClassCastException: <String, > is not a javaType

I made some investigation myself, I found that the g(rouping)-function expects that the arguments are AviatorJavaObjects (fx. p.dom) and just fails when it receives a raw string. But keyGet2 returns string so it feels that it is impossible to use keyGet2 within a group match function.

PS. the exact same configuration: same policies, groups, model, request works as intended in the online editor, https://casbin.org/en/editor/
