Attempt to call method 'sendExtendedOpcode' (a nil value)

[Lopaskurwa]

Getting this attempt to call method 'sendExtendedOpcode' (a nil value) on my spell, strangely i noticed for some reason it happens only for few people but for some it works perfectly, for some people are just executing the spell that does nothing just applies cooldown, but for some works perfectly and i see in terminal it gives this error and legit i dont understand how its possible, speculation is that some people losing player status somehow, because getting prints saying "Caster is not a Player object." this is the spell sendextendedopcode that i use

local function sendExtendedJson(player, action, data)
    if not player or not player:isPlayer() then
        print("Caster is not a Player object.")
        return
    end

    if data == nil then
        data = {}
    end
    player:sendExtendedOpcode(config.opCode, json.encode({action = action, data = data}))
end

And this is in data\lib\core\player.lua

function Player.sendExtendedOpcode(self, opcode, buffer)
    if not self:isUsingOtClient() then
        return false
    end

    local networkMessage = NetworkMessage()
    networkMessage:addByte(0x32)
    networkMessage:addByte(opcode)
    networkMessage:addString(buffer)
    networkMessage:sendToPlayer(self)
    networkMessage:delete()
    return true
end

Legit lost and dont know how its even possible

Interesting factor is that it seems that relog fixes the issue after it starts happening again after multiple spell uses

Hi, you can try sending cid and check userdata.

local function sendExtendedJson(cid, action, data)
    local player = Player(cid)
    if (not player) then
        return
    end

    if data == nil then
        data = {}
    end
    player:sendExtendedOpcode(config.opCode, json.encode({action = action, data = data}))
end

Why dont pring some player data in the error? But sendind player in the parameter doesnt seems correct. Its aleays better send cid and retrieve player later

Umm just found out it looks like spamming of that spell can be causing extendedopcode not to send it, because after high spam of it, it breaks that would explain why it was happening only for few people and fixes after a relog and breaks again if you spam it like crazy

Could be, but i would still do what i suggested.
