FiveM development. Step by step.

From an error log to an understandable change.

A Lua error is often the visible end of a longer chain. Upload the affected files in AI chat, include the complete error and describe how to reproduce it. This turns a guess into a hypothesis you can test.

What you can do

Useful debugging connects the error message, the triggering action and the actual version of your resource.

Review a resource in AI chat
VelonLabsExample
↥ garage.zipZIP
client/main.lua
22 · attempt to index a nil value

Explain the error. Check context. Revise the resource.

Upload + debugging

Describe a reproducible failure

Specify the player action and whether the message appears in the server console or the F8 client log. An “attempt to index a nil value” alone does not show whether data is missing, an export runs too early or a framework integration is wrong. Include the file path, line number and relevant log output.

Upload connected source files

A ZIP resource or supported individual files provides context for imports, events and configuration. Remove passwords, API keys and personal data before uploading. Also describe the start order and external resources missing from the upload. Encrypted or unreadable code cannot be analysed like open source files.

Verify the correction deliberately

Ask for an explanation of the cause and the change. Compare affected code with the previous version, then repeat the original failure first. Test nearby cases afterwards: a second player, a missing database record or a resource restart. A disappearing error log is not by itself proof of correct behaviour.

For your next task

A useful debugging request

Parking a second vehicle produces server/main.lua:84: attempt to index a nil value. Here are the resource and log. Investigate the cause, preserve existing events and explain the smallest necessary change. List the cases I should check on my test server afterwards.

Check before moving on

  • Include the complete error and context
  • Name your framework and external dependencies
  • Remove secrets from uploads
  • Retest the original failure and related cases

Scope and limitations

Analysis relies on the code and context you provide. VelonLabs cannot see your running server without that information. A proposed correction needs verification under your actual conditions.

Common questions

Can I upload complete resources?

AI chat accepts ZIP resources and supported individual files. The upload interface shows current size and format limits.

Will it fix my live server automatically?

No. You receive analysis and editable changes. Testing and deployment to your FiveM server remain under your control.

For your next step

01

Create FiveM scripts with AI

Plan and create FiveM Lua scripts with VelonLabs. ESX, QBCore, Qbox and Standalone: turn a specific request into editable source code.

See workflow and examples →03

FiveM Config Editor for Lua, JSON, YAML, TOML & INI

Edit supported FiveM configurations visually and in source view. Review values, understand the structure and download changed files as ZIP.

See workflow and examples →04

FiveM NUI preview

Review FiveM NUI interfaces in the VelonLabs browser preview. Check layouts, appearance and supported interactions before testing in game.

See workflow and examples →05

FiveM Agent Mode

Structure larger FiveM tasks with VelonLabs Agent Mode. Connect your brief, plan, file changes and result review in one development workflow.

See workflow and examples →06

Project knowledge & notes for your FiveM workflow

Keep framework context, project instructions and notes in one place. Organise FiveM knowledge for recurring development tasks with VelonLabs.

See workflow and examples →07

GitHub integration for FiveM

Connect GitHub to VelonLabs.dev. Work on FiveM resources in Agent Mode, review file changes and deliberately sync them back to your repository.

See workflow and examples →08

FiveM teamwork

Build FiveM resources together. Invite members to VelonLabs.dev, share workspaces and repositories, and assign Viewer or Editor roles.

See workflow and examples →09

Connect your FiveM server

Connect your Linux or Windows FiveM server to VelonLabs.dev. Edit a workspace copy and sync reviewed files with backups and deployment rollback.

See workflow and examples →10

Create FiveM assets with AI and browser editors

Start with an AI chat prompt, then edit vehicles, clothes, characters, props and textures in the relevant VelonLabs editor.

See workflow and examples →11

FiveM Blueprints

Scripts from the VelonLabs Store come with a personal blueprint. In AI chat or Agent Mode it becomes a new script built to your project rules.

See workflow and examples →12

FiveM Workspace

In the VelonLabs Workspace you connect AI chats, agent tasks, notes, editor projects and blueprints on one board, edit files and work as a team.

See workflow and examples →13

VelonLabs Control

Bring scripts from AI chat and exports from the editors to your FiveM server over SSH, start resources and test in game without copying files by hand.

See workflow and examples →

Your project. Your next step.

Describe your idea or upload an existing resource. Continue working on the source code and test the result on your server.
