What generates "Could not find object" message?

[animats]

I'm getting the error channel message:

[11:39] Testi - NPC trainee  14.0: Could not find object ''.

That's a new one, not on the list of known script run-time errors.

It's being triggered by my scripts, but which LSL call can generate that?

For what it's worth, it's happening during startup, after script reset, as my scripts are sending link messages to find each other and hook up. I used to have all the scripts in one prim, but I'm converting to a system where they're in several prims, for ease of modification. So it probably has something to do with inter-prim communications.

(Somebody got this message back in 2008, but the archived posting doesn't answer the question.)

Without knowing more than what you have said, my first guess is that llMessageLinked is trying to send a message to a link that it cannot identify, although I would have expected the attempt to simply fail silently in that case.  If you look at the caveat notes for that function, you'll see that there are several cautions about caps of one sort of another.  I suppose it's possible that the system is complaining because you have been sending too many messages too fast.  Even my more ambitious scripts have rarely hit one of those caps, and I have never seen a message like yours, but I guess there's always a first time.

Wrong llMessageLinked prim destination is a very real possibility.

I may have a race condition at startup, where I sent a message to a script that's resetting.

If that's the case, you could try deliberately delaying the messages a bit to give the scripts time to settle down, or maybe ask each child script to send a ping to the root on rez, to verify that it's alive and ready to work.

"Could not find object ''." is typical of rez failure due to object not existing in inventory.

That makes sense, except that this set of scripts doesn't rez anything. More on this later.

llRezObject and llRezAtRoot can produce that message.  The '' at the end of the message seems to indicated that an empty string was passed as the first parameter to the function call.
