Question

SCRIPT ERROR: #sessionmanager/server/host_lock.lua:25: attempt to compare number with nil
[script:sessionmanage]> handler (#sessionmanager/server/host_lock.lua:25)
the script:
-- whitelist c2s events
RegisterServerEvent('hostingSession')
RegisterServerEvent('hostedSession')
-- event handler for pre-session 'acquire'
local currentHosting
local hostReleaseCallbacks = {}
-- TODO: add a timeout for the hosting lock to be held
-- TODO: add checks for 'fraudulent' conflict cases of hosting attempts (typically whenever the host can not be reached)
AddEventHandler('hostingSession', function()
-- if the lock is currently held, tell the client to await further instruction
if currentHosting then
TriggerClientEvent('sessionHostResult', source, 'wait')
-- register a callback for when the lock is freed
table.insert(hostReleaseCallbacks, function()
TriggerClientEvent('sessionHostResult', source, 'free')
end)
return
end
-- if the current host was last contacted less than a second ago
if GetHostId() >= 1 then
if GetPlayerLastMsg(GetHostId()) < 1000 then
TriggerClientEvent('sessionHostResult', source, 'conflict')
return
end
end
hostReleaseCallbacks = {}
currentHosting = source
TriggerClientEvent('sessionHostResult', source, 'go')
-- set a timeout of 5 seconds
SetTimeout(5000, function()
if not currentHosting then
return
end
currentHosting = nil
for _, cb in ipairs(hostReleaseCallbacks) do
cb()
end
end)
end)
AddEventHandler('hostedSession', function()
-- check if the client is the original locker
if currentHosting ~= source then
-- TODO: drop client as they're clearly lying
print(currentHosting, '~=', source)
return
end
-- free the host lock (call callbacks and remove the lock value)
for _, cb in ipairs(hostReleaseCallbacks) do
cb()
end
currentHosting = nil
end)
EnableEnhancedHostSupport(true)

correct the block:
if GetHostId() >= 1 then
if GetPlayerLastMsg(GetHostId()) < 1000 then
TriggerClientEvent('sessionHostResult', source, 'conflict')
return
end
end
here you need to check for nil or not allow nil when comparing numbers:
local HostId = GetHostId() or 0
if HostId >= 1 then
if GetPlayerLastMsg(HostId) < 1000 then
TriggerClientEvent('sessionHostResult', source, 'conflict')
return
end
end
