When the base is removed after the event ends, conflicts with other plugins occur.

It conflicts with other plugins that use the OnEntityDeath hook, causing a null error. player, info
I tried debugging to see if null occurs in entity.name, but
It was of no use and a null error occurred in a situation where the base was destroyed, causing serious lag on the server.
Is there any solution?
I would like to know if there is a point I am noticing, a debug method, or the cause.
Note: An error occurs in Bearrels created by redBDGR.
Create a debug plugin
I checked, but an error still occurs in OnEntityDeath.

what is the error

Failed to call hook 'OnEntityDeath' on plugin 'dosiin v2.2.3' (NullReferenceException: Object reference not set to an instance of an object)

you need to null check your code then

Quote

if (!entity || info == null) return;

if(player != null || entity != null || info != null)
    {
    if(entity.name != null)
    {

I tried it, but the error keeps occurring. Is there anything else I should check?

that's close, but you need to use what I suggested

        void OnEntityDeath(BaseCombatEntity entity, HitInfo info)
        {
            if (!entity || info == null)
                return;
            if (!entity.name.Contains("barrel"))
                return;
            if (UnityEngine.Random.Range(0f, 1f) <= ConfigFile.chanceOfBear)
            {
                SpawnBear(entity.transform.position);
                BasePlayer player = info.InitiatorPlayer;
                if (player != null)
                    PrintToChat(player, msg("Bearrel", player.UserIDString));
            }
        }

Thank you. I think it has now been resolved in that plugin.
The problem is that I have written a plugin for the purpose of linking to the web and generating statistics.
I get the same error.
Please one more time.

void OnEntityDeath(BaseCombatEntity entity, HitInfo info)
        {
    BasePlayer player = info.InitiatorPlayer;
    if (!entity || info == null)
    return;
    if(entity.name.Contains("barrel"))
    {
    BarryWebRequest2?.Call("BWR2","kostat","barrel");
    }
    else if(entity.name.Contains("scarecrow"))
    {
    BarryWebRequest2?.Call("BWR2","kostat","scarecrow");
    }
    else if(entity.name.Contains("scientist"))
    {
    BarryWebRequest2?.Call("BWR2","kostat","scientist");
    }
    else if(entity.name.Contains("stag"))
    {
    BarryWebRequest2?.Call("BWR2","kostat","stag");
    }
    else if(entity.name.Contains("bear"))
    {
    BarryWebRequest2?.Call("BWR2","kostat","bear");
    }
    else if(entity.name.Contains("boar"))
    {
    BarryWebRequest2?.Call("BWR2","kostat","boar");
    }
    else if(entity.name.Contains("wolf"))
    {
    BarryWebRequest2?.Call("BWR2","kostat","wolf");
    }
    else if(entity.name.Contains("chicken"))
    {
    BarryWebRequest2?.Call("BWR2","kostat","chicken");
    }
    else
    {
    return;
    }
    }

Every time an NPC is captured, the plugin is called and counted, but an error occurs for the same reason.

yes no problem.

check before the cast

if (!entity || info == null)
    return;
BasePlayer player = info.InitiatorPlayer;

you should use entity.ShortPrefabName instead of entity.name too

You are truly amazing.
I don't know English and am very interested in programming, but I was at a loss after referring to various plugins and contacting chatGPT.
It has been resolved.
thank you so much.

The second question was simply a matter of order.

no problem enjoy
