You can write your topic however you want, but you need to answer these questions:

  1. **What do you want to achieve? : want to solve this bug

  2. What is the issue? :
    utility snippet
    local PlayerService: PlayerService = {
    byteNetData = {},
    config = {
    dataLoadTimeout = 12,
    },
    }

PlayerService.byteNetData.Communication = ByteNet.defineNamespace(“Communication”, function()
return {
ClientLoaded = ByteNet.definePacket({
value = ByteNet.struct({
success = ByteNet.bool,
}),
}),
ServerLoaded = ByteNet.definePacket({
value = ByteNet.struct({
success = ByteNet.bool,
duration = ByteNet.float32,
}),
}),
}
end)
client snippet
local Utils = require(script.Utils)

function PlayerService.SendClientLoaded(self: PlayerService)
Utils.byteNetData.Communication.ClientLoaded:send({ success = true }) – HELLO SERVER?
end

Utils.byteNetData.Communication.ServerLoaded:listen(function(data)
PlayerService.status.isServerLoaded = true – SERVER ACTIVATED ME WOO HOO!
PlayerService.status.success = data.success
PlayerService.status.duration = data.duration
end)

server snippet
Utils.byteNetData.Communication.ServerLoaded:send({ success = true, duration = durationTookToInit }, player)

Utils.byteNetData.Communication.ClientLoaded:listen(function(player: Player, data) – HAPPENS AFTER CLIENT LOADS
if not data.success then
PlayerService:HandleLeave(player, “Client failed to load data”, false) – Like, client might got a device problem or smth occurres rarely
end
end)

i tried literally everything and its the last. posting to forum.

This error usually means your ByteNet packet structs don’t match between client and server.

attempt to index nil with 'read' happens when the receiver tries to decode data using a different struct than what was sent.

I would check if the Client and server use the exact same namespace + packet definitions, same fields, same order, same types. And if Utils.byteNetData comes from the same ModuleScript, not redefined separately

If even one field is missing or ordered differently, ByteNet will throw this error.
