well, xlog("$(var(Event){s.rm,"})"); shouldn't have " " unless it's just you logged that this way - so at the end we should have

route(CGR_AUTH_REPLY);

I don't see any problems in that part of config and don't understand which other parts can generate such messages.

According the fact you receive error from tmx module, that may be
t_continue("$var(id_index)", "$var(id_label)", "CGRATES_AUTH_REPLY")

But I'm not sure, can't say anything bout that, construction looks legitimate
