Hello i have a problem and it says attempt to call a nil value (upvalue 'successCB') i have tried different methods but didn't work so i want to know if you guys could help me
Here is the a picture of error
and here is main.lua:20
RegisterNUICallback("main", function(data)
SetNuiFocus(false, false)
QBCore.Functions.Notify("Authorization Success" , 'success', 7500)
successCb()
end)
below also is a short part of the code JS code
$("#submit").click(function () {
let inputValue = $("#input").val()
if (inputValue.length > 4) {
$.post("http://vny-lvaultcodes/error", JSON.stringify({
error: "Code cannot be greater than 4"
}))
$("#container").fadeOut(250);
return
} else if (!inputValue) {
$.post("http://vny-lvaultcodes/error", JSON.stringify({
error: "You need to type a 4 digit code for submitting."
}))
$("#container").fadeOut(250);
return
}
if(inputValue == code){
$.post('http://vny-lvaultcodes/main', JSON.stringify({text: inputValue,}));
$("#container").fadeOut(250);
} else {
$.post('http://vny-lvaultcodes/failed', JSON.stringify({}));
$("#container").fadeOut(250);
}
also below it is a function to open the ui and stuff
function openCode(show, code, success, fail)
successCb = success
failCb = fail
display = true
SetNuiFocus(true, true)
SendNUIMessage({
type = "open",
code = code,
})
end
I'm unfamiliar with fivem but looking at the documentation, I think you've defined your callback incorrectly.
https://docs.fivem.net/docs/scripting-manual/nui-development/nui-callbacks/
RegisterNUICallback not only takes a data value but the callback as well (cb in the document).
In your case successCb would be nil thus when you call successCb() it produces the error.
As such, I'd try one of the following:
RegisterNUICallback("main", function(data, successCb)
SetNuiFocus(false, false)
QBCore.Functions.Notify("Authorization Success" , 'success', 7500)
successCb()
end)
RegisterNUICallback("main", function(data, cb)
SetNuiFocus(false, false)
QBCore.Functions.Notify("Authorization Success" , 'success', 7500)
cb()
end)
Hopefully that helps.
