[HELP] NUI callbacks not working after the update

jsfour · 2018-12-07T21:05:45.555Z

All of my scripts that are fetching a table from the database and then returning it to the javascript are broken.

They’re returning empty. I have no idea why or what’s causing it but they’ve been working fine until today after the small update.

I’ve solved this by encoding the table on the server and then parsing it in the javascript. Is this intentional? Is it even the update that’s causing this?

# LUA
RegisterNUICallback('fetch', function(data, cb)
  ESX.TriggerServerCallback('jsfour-mdc:fetch', function( d )
    -- d isn't nil it has all the data in it
    cb(d)
  end, data)
end)

# Javascript
$.post('http://jsfour-mdc/fetch', JSON.stringify({type : 'person', lastdigits : lastdigits}), function(cb) {
	console.log(cb);
    -- When logging the cb it returns empty which it hasn't done before
});

EDIT:

After some testing it seems to break when trying to cb nested tables. resultUser and resultRecord are tables fetched from the database.

local array = {
   userinfo = resultUser,
   records = resultRecord
 }

cb(array)

Can you provide a minimal repro that breaks? It seems quite odd for only nested data to be broken, since this is done using local code and not code in the CEF framework.

Hi! Really appreciated that you’re taking your time to look into this!

I’ve made a small repo on github, I’ve also posted screenshots of what it returns.

And like I said earlier. If I do cb(json.encode(array)) it works either way. My scripts have been working for months until yesterday so it’s really weird. I mean it’s not a huge deal for me to encode everything.

But I want to get confirmation that this is infact something you’ve changed until I start to fix all of my scripts
