Errors KeyNotFound, NullPointer & SetDestination

Pending 1.0.8

    The console is full of KeyNotFoundExceptions, NullPointerExceptions and finally SetDestination can only be called on NavAgent placed on a NavMesh. THis only occurs till Bot's have to respawn. On first spawn Wave after Server Start everything is fine. But when they have to respawn the error's appear in the console, but they do respawn and work as intended. It is just, the console is full of these exceptions that occur like 20 times per tick.

    My first question to give a better error code or possibly fix it myself, how the heck can I enable true Exception message, with the actual line and function that had an Exception? I couldn't figure it out.

    Hi,
    Thanks for reporting. If there are issues I'll certainly fix them.
    What version of BotReSpawn are you running?

    If you have server log to file enabled could you DM me a copy of your most recent log?
    If not, if you could paste the relevant errors that'd be great.

    But as said the errors are without line and function information otherwhise I could fix them myself

    I currently don't have a copy of the Exception for NullPointer oder KeyNotFound, but they were the same without line/function reference. That's I wanted to first ask how to get a better logging of the exceptions thrown.

    The best logging you'll be able to get is the server log to file.
    You can enable that by having -logfile "log.txt" in your startup script, after RustDedicated.exe.

    For example - RustDedicated.exe -batchmode -nographics -logfile

    If you could enable that then send me a copy of the log file before restarting/shutting down the server, that'd be great. (the file is overwritten each time).

    In the mean time, if you see the KeyNotFound error feel free to paste here. It should have useful info with it.

    Hi,
    Looks like it's caused by scientist_roam npcs, so most likely BotReSpawn.
    The locations all seem to be bunched around ( 70, 50, -850 ) - Is there anything unusual about that area of the map?
    Do you have custom spawn points around that location, or just a random-spawning profile?

     

    Thank you!

    It is where the LaunchSite is located. I deactivated the default LaunchSite profile "autospawn - False" but nothing changed. Then I also saw this error

    Hi,
    That first one is a null error in the `/botrespawn info` command, when looking at something that isn't an npc.
    I wasn't aware of that one so it's now fixed. Thanks for reporting!

    The second paste is about scientists from the cargoship, so not related to BotReSpawn.

     

    Sounds like there's some issue with the LaunchSite area, which is good because that's vanilla - I can go and see if I can do something about it.
    That's really helpful.

    Any spam relating to that profile should stop if you set the profile AutoSpawn false, then reload the profile.
    The reload is essential to kill off the current live npcs.

     

    I haven't seen your keynotfound error yet so if you're willing, sending me a full console log from the very end of a server cycle, right before restart, would be super helpful.

    Here ya go. Thx for taking a look into it, as all these Exceptions catched by net framework really have a big hit on the tickrate of the server

    No trouble at all - It needs fixed.
    I think I'm going to have to replicate your setup to get this figured out.
    Is your map free or procedural? If so could you share that info with me?

    If it's paid please DM me the details and I'll reach out to the author about testing with it.
    Thanks for the help and patience!

    Thanks for the info.
    I've fired up your map and data files on a test server - so far without issue - but I think I know where the errors are coming from and how to handle it.
    While BotReSpawn shouldn't be able to throw errors, and I plan to address that, I think the root cause is just too much pressure on the server.
    Looks like your data files are calling for over 1200 npcs, which is quite a lot, and probably just too much once the server's in full swing with population and high entity counts etc.

    Anyway...DMing you a copy shortly which should, hopefully, stop there being any errors but, unless I'm wrong, I think it'd be advisable to pull the numbers back

    Okay awesome thx. I totally understand that it is a bit cranked up on the numbers, I will play a bit around with your new version then. Thx for all your support and time

    No trouble at all.
    I'm trying to let it run to provoke the errors, (with some debug) just to confirm I've caught it, but nothing's printed yet.
    I'll send it over as soon as I get confirmation ^. 👍
