Subject: HTTP Module Not Available in CC:Tweaked (Minecraft 1.20.1) Despite Successful Internet Test

Hi CC:Tweaked Team,

I'm running into a persistent issue with the http module in CC:Tweaked (1.20.1). I’ve tried everything I could think of, but nothing seems to resolve the problem. Here’s a breakdown of what’s happening:

Issue:

Whenever I run a script that uses the http module, I get the error:

HTTP module is not available! Make sure your CC:Tweaked setup has internet access enabled.

Setup:

• Minecraft Version: 1.20.1
• CC:Tweaked Version: (1.113.1)
• Host: Single-player world (and also tested on a BisectHosting server)
• Using a Command Computer with an Internet Modem (wired correctly and powered)

What I’ve Tried:

1. Internet Test: I ran a test script using the modem, and it successfully connected to https://www.google.com and returned HTML content. This suggests that the modem and internet access are working.
2. Config Settings:
   • I checked for cc-tweaked.cfg and ensured:

     enable-http = true  
     

3. Single-Player Test: Ran the script in a single-player world (with no server restrictions), but the same error occurred.
4. Reinstallation: I tested with a clean Minecraft instance (only CC:Tweaked installed), but the error persisted.
5. API Script Verification: My script attempts an OpenAI API call using http.request() and http.get(). The script is formatted correctly and worked for others on the same CC:Tweaked version.
6. BisectHosting: I confirmed with my host that they do not block external HTTP requests, and I performed an HTTP test which succeeded.

Odd Behavior:

• Despite the modem passing the Internet test, the http module still returns the "not available" error, as if the module is entirely missing or disabled.
• Running require("http") in a Lua test also fails with "module not found", which is unexpected since http should be built into CC:Tweaked.

I’ve spent a lot of time troubleshooting this and would really appreciate your insight. Thanks in advance.

I meant with the ingame modem, i was under the belief that I needed to connect that to a computer to access "internet". I changed the script to how you said it should be, yet I still get "ChatGPT: Error: Failed to connect to the OpenAI API." I assume this error is out of CC:T's control?

CC:T has no require("http"). It is one of the base globals injected if the config has http enabled.

Most likely issue: You are editing the defaultconfig instead of serverconfig. You should be looking for worldname/serverconfig/computercraft-server.toml, not some cc-tweaked.cfg. This is a common issue, at least in MCCM.

Can you clarify what you mean by the command computer with internet modem though? Are you meaning an external hardware modem, or some mod addon? CC:T should have network access by default, without anything extra (unless, again, disabled in the serverconfig).

No, that error is part of your program, and is misleading.

When you make an http request using http.post, it returns up to 3 values. In the case of a successful request, it returns just the request handle. If the server responds a 4xx or 5xx (or doesn't respond at all), it returns nil, "error message", request handle.

In other words, you should be doing something like this:

local handle, err_msg, err_handle = http.post(...)

if not handle then
  if err_handle then -- server gave us 4xx or 5xx
    printError(err_handle.readAll()) -- you may wish to serialize this or write it to a file or something. Sometimes API errors can be quite long.
    err_handle.close()
  end
  error(err_msg)
end

-- Making it to this point means successful connection
local data = handle.readAll()
-- ...

Your current handling of this assumes that every failed http request means a failed connection, but the server is likely responding that you've done something incorrectly.

And yeah, the ingame modems are only for in-game communications. Communications between CC computers and peripherals (monitors, printers, other CC computers, etc.). If you have http enabled, all computers can access it regardless of if they have a modem attached.
