Es_extended/client/functions.lua:992: attempt to call a nil value (field '?')

[VORT3XONE]

Hey,
im currently running a FiveM Server and im getting this Error like all 20 minutes in my F8 console:
@es_exteded/client/functions.lua:992: attemp to call a nil value (field ‘?’)
The code in the lines is the following:

RegisterNetEvent('esx:serverCallback')

AddEventHandler('esx:serverCallback', function(requestId, ...)

    ESX.ServerCallbacks[requestId](...)

    ESX.ServerCallbacks[requestId] = nil

end)

line 992 is ESX.ServerCallback[requestId(…)

Someone got any fixes for that or soe tips?
Thanks.

The problem doesn’t come from es-extended but from a script you use… Check in F8 console or server console which one had a problem
