FiveM Error Decoder
Paste the first relevant error. The tool matches known patterns and returns practical checks without uploading your log.
Pattern matching only. Not AI, a scan, or a technical diagnosis.
How to read a FiveM error
- Copy the first error from the server console or client F8 console, including the resource name, file and line number when available. Remove passwords, tokens and personal details.
- Paste up to 12,000 characters and select Match error. The checks cover Lua nil values, missing exports, unsafe network events and missing resource files.
- Check the reported location and follow the suggested checks in your own project. Make one change at a time, reproduce the problem and keep the original log.
A fictional example
Use a sample error to load a demo message about a missing Lua player value. Matching it shows where to inspect the assignment; it does not confirm why the value is missing in your project.
What the result can tell you
This tool reads only the text you paste and processes it in your browser. It cannot inspect your files, server or database. A matched pattern is a starting point, and an unknown pattern does not mean the server is healthy.
