QuestLog exceptions and QuestLog updates

[Studio60]

When HB is not running it can happen that some object (probably the LocalPlayer) goes invalid so querying the ProfileHelperFunctionsBase() for a quest causes exceptions. I do have a Lua-based fallback ready, but I need to know how I can check before querying ProfileHelperFunctionsBase if the request would fail. I don't want to a try/catch logic to my code. Is "!StyxWoW.Me.IsValid" enough as a check or is the exception caused by some other object ?

Styx.InvalidObjectPointerException: Cannot read a descriptor on an invalid object.

Personally I use Me.IsAlive in my Cr's to check whether I am in game and valid.
