[C# & Lua] Having a lot of problems with exports

FiveM Resource Development & Modding Discussion

Sooo, I’m trying to use exports to call lua functions using C#, but I keep getting an error saying that the export doesn’t exist in the dictionary. The lua and C# files are in the same resource, so I don’t know if that’s a factor that prevents me calling the exports.

Here is my code:

Server C#:

var res = new ExportDictionary()[API.GetCurrentResourceName()].httpRequest("https://google.com/",
    "GET", new Dictionary<string, string>(), new Dictionary<string, string>());

server.lua:

function httpRequest(url, method, data, headers)
    local debug = config.debug
    local data = nil
    PerformHttpRequest(url, function(status, text, headers)
        data = {
            status = status,
            content = text,
            headers = headers
        }
    end, method, json.encode(data, headers))
    while data == nil do
        Wait(1)
    end
    return data
end

__resource.lua:

server_script 'server.lua'
export 'httpRequest'

server_script 'server.net.dll'

C# error:

I cleared cache server and client side and it did nothing to help.
I also referred to other topics on the website and they didn’t help me at all…

server_export? also don’t create ExportDictionary yourself, just use Exports in BaseScript.
